Allison - you should definitely do it! I know this is different, but I went to Cathe's road trip last year all by myself and knew absolutely no one and didn't know if I would know what to do, etc. But of course it went just great and I know if you go ahead and do it, you will be so happy that you did!
I wish it was nearby where I lived -- I would cheer you on!! Good luck and I hope everything goes well. Looking forward to seeing you and Tracey at the next road trip!!
