I've always wondered how the meets work. Is it only for people in a certain area? I can't imagine someone flying out for one
Oh yes, we have flown out to meet DISers.
Just last year in September we had a get together with me, Betsy, Ann, Ann's two sisters Susan and Mary, Colleen and Cally at Disney

(along with other various and assorted family members who came along for the fun)
In January of 2007 we did a Threadkiller 4 day Disney Wonder cruise with myself and my husband, Ann and Tom, Susan and Mary and Betsy and Mike. (along with a bunch of other really nice DISers that we met up with on our cruise thread over on the Cruise board)
It was great
I've driven to Chicago and met up with KimRaye before and we've also met half way.
Betsy and Mike and my daughter Liz and I got together at Niagara Falls a couple summers back for a weekend.
There have been other meetings amongst various other groups of the threadkillers too.
So yes, we ARE crazy enough to fly out or drive long distances to get together.
I wish we could do it again real soon.
There are also other "general" dismeets that are held in cities all around the world.
Those are usually open to any DISers who want to go and meet up in person with others they have met on line.
