I suppose I should have recommended this one about a month ago, but I didn't have posting privileges then. Anyway, if you happen to be in the Kansas City area during the next few weekends, this can be fun.
And I know that you want to see these guys.
I don't live near Kansas City, but I have been lucky enough to be in the right place at the right time on three occasions.
Anyway, I'll have more things to recommend later, mostly involving Halloween.
