I could only wish for a reptile show in reasonable driving distance. But just like you, I cannot stand "crowds". The older I get, the worse it gets. I can't stand people bumping into me or crowding.
So you bought nothing? GREAT self control !!!
You know, mine has gotten worse with age as well. Honestly it was so busy I was not able to even enquire about anything, at least enough to make me feel comfortable buying.
