All signed up on the Listserv and reading the emails! I was in the first 3 caravans (1994, 1999 and 2003) and am looking forward to this one, too! In the 2003 caravan for the 50th anniversay I was the local leader from the Fort Myers area. I've volunteered to help with this coming one also.
If you've never been in one of these caravans, it's definitely worth doing it at least once!
