This year (2013) marks the 100th anniversary of the Lincoln Highway. Classic Car Club of America is doing a roadtrip the entire length. At this point I don't know how many are going the entire distance, but a number of cars are signed up to do at least a portion. The road starts in New York and ends in San Francisco.

The Lincoln Highway Association is also commemorating the anniversary, with tours starting on either end and converging in Kearney, Nebraska on June 30.

Talk about the ultimate road trip!
