As in all amateur astronomy star parties, the weather has a large influence on turnout and participation. While I was not at the 2008 RTMC, nor the 2007 RTMC, I regularly attended from 1998 to 2006. Those years were enjoyable and I am certain that future RTMCs will be just as much fun, as long as the weather cooperates. I am certain that the bad weather this year put a damper on both vendors and participants.
I have travelled cross country to Stellafane twice. Both times it was rainy. I have never been able to do any nighttime observing at Stellafane. But I always enjoyed myself talking with the people there.
Give astronomy star parties and expos another try....when the weather is better.
