COMP Cams Thumpr Retrofit Hydraulic Roller Camshafts
COMP Cams is bringing back the musclecar soundand it's nastier than ever! Few things grab our attention at a car show or cruise night more than a car with a thumping high performance idle. In an ongoing quest to provide you with the performance and sound you demand, COMP Cams' engineering team proudly introduces the Thumpr retrofit hydraulic roller camshafts. They are a series of camshafts designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles. Each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. COMP Cams Thumpr Series camshafts feature a cutting-edge hydraulic roller design that delivers a substantial power increase over identical hydraulic flat tappet grindswithout sacrificing reliability or ease of maintenance.

a great guide to DC treasures
Format: Flexibound
This is not a guide book in terms of giving you directions and hours of operation, but it would be a wonderful first step in planning a memorable trip to the nation's capitol.
Nineteen themed trails are given, seven in and around the Mall, six nearby, two across the Potomac and two farther afield. Themes include animals (Rock Creek Park, National Zoo, the George Washington University hippo (statue), the National Museum of Natural History, Owney the stuffed dog at the National Postal Museum, Oxon Hill Farm, Kingman Island and the Franciscan Monastery and National Cathedral -- and a blurb about presidential pets), statuary, music, food, horticulture, power, sports, ghosts, architecture, literature, transportation etc.
As you can tell these aren't walking tours. Instead each theme gets four pages filled with photos, drawings, fun facts and information about festivals, artifacts, history and spectacle.
I try to get to WDC once or twice a year, yet I still found plenty of interesting ideas for further exploration.
If you are planning a visit (with or without kids),this would be agreat way to help them choose a few things they'd like to see. Information is presented in a friendly way but is not dumbed down.
There is an adequate, if incomplete, index. It would be useful to have a calendar of all the events listed too.

Great book of fun facts about nation’s capital!
Format: Flexibound
I take my 3 boys (3, 5, 7) to Washington DC each year. This is a wonderful book full of fun facts for our nation’s capital. If you are looking for a kid version of a travel book that maps you through neighborhoods, etc., this is not it, but what kid would like that kind of book? That’s what grown-ups are for - mapping out the trip. Rather, this is a great supplement to read at bedtime to learn all sorts of facts about the city - from the historical pets of the White House to the error in the inscription on the Abraham Lincoln memorial. Really - these are great facts for adults also! Each page is a separate set of topics on its own, so it’s easy to read just a few pages at a time. Also there are great illustrations to hold the younger audience’s interest as well. This is a great buy and a must-have to get kids ready for their trip, or to read during it, or after (or all three!).

Happy Wanderer
Format: Flexibound
City Trails is not a guided walking tour (like the Freedom Trail here in Boston) of the Metro DC area. No addresses or street names are noted in the blurbs. To actually visit any of these places, you’ll have to consult a real map. For instance, the chapter “Statue City” highlights notable statuary around town. But the Capitol Building statues (in SE DC) are far from the Cathedral ones (in NW DC.) The themed groupings (G-G-G-Ghosts, Animals Around Town, Water World and more) are less maps to any place and more of an interesting overview of our Nation’s amazingly diverse and action-packed city. It’s best read as a primer on experiencing the flavor of the city (I lived and worked there.) It reads more along the lines of the “Weird But True” series made famous by National Geographic for Kids.
I don’t see this being of value to tourists in town for a limited time whose sightseeing is going to include major attractions like government buildings (White House, Capitol), museums (Smithsonian), some monuments (Jefferson, Lincoln, Washington) and other popular sites (Ford’s Theater.) This guide is actually best suited for the Metro-area (WDC, MD and VA) resident – child or adult - who wants a deeper dive into their hometown’s off-the-beaten-path sights and stories. A well designed and written book of historical trivia.
