I put this up in the Classic Minis section on NAM but wasn't sure if you heard about this yet. World Mini Raids - Classic Minis from France are touring the US along Route 66.

This trip is planned for 3 weeks. Thursday, April 21 to Sunday, May 15, 2011.
Their group will include 9 crew of 2 persons and travel more than 6000km.

You need to check them out - see if you can ride along with them if they reach your neck of the woods! Their website is in French, but most web browsers will translate http://www.world-mini-raids.fr/
