Prides are pretty much always like that. I’m prioritizing them next year because of it! Cincinnati Pride specifically, it is outdoors though. I’ve noticed a huge overlap for a lot of types of cons. I’ve done retro gaming cons, Comicon, anime cons and prides and retro gaming cons have the least overlap, but with your stuff you’d do great.
I have vended at 2 Pride events and I nearly sold out at both of them! This year is my 3rd pride event in October and Im SO EXCITED!!! I sell frogs though so im not sure on the nerd part of it
