Thanks, HuntsvilleTX, I'll be looking forward to your and others' reports ...;^)
I made it from Lafayette to Sacramento. Missed the one in Stockton. The crowds were not huge but they were enthusiastic. The scheduling was a little too ambitious.
I'm sorry I can't go all the way to Washington, DC.
Just a suggestion. The Lafayette to Vacaville caravan went great, but the cars were more spread out after that. It would help to have a list of all the caravaners and to give out the cell phone number of a passenger in the lead car who can direct the traffic.
