If you're referring to furry conventions, then I'll chime in and say there are plenty of hot people in the furry community. They just usually aren't the ones who get mocked on social media for being awkward.
I'm pretty sure you might get shot if you tried this in Texas. Some crazy would get mad about how dinosaurs were invented by Satan to mislead people into believing in evolution and therefore wearing a dinosaur costume makes you agents of the devil or something.
In the big cities? Dalls? Austin? Nah. People might look at you weird.
Anywhere else? ...Might have to give some killjoy 15min to an hour to call the cops
