A fellow on twitter named Quixbull is reporting that Growly was forcibly removed from a convention by security.
I tried following up for answers but got nothing from this individual. However, he tweeted a week earlier that he was going to AZFC in Phoenix.
Growly has gone to AZFC repeatedly before, including organizing parties just outside the con a few years ago. Looks like ONE MORE CON that Growly got the boot from. If so, good fucking riddance.
Any comments should go to the main Growly thread.
