I'm a fan and supporter of #BillsMafia. Granted, I'm not as hardcore as others but I've had numerous interactions with Del, co-founder of BillsMafia, and they do nothing but great stuff for Roswell! Props to them for running with it and supporting a great cause.
For fun, I made a mock poster of "GoodFellas" for BillsMafia. It received the attention of Fred Jackson and Nick Barnett--both whom re-tweeted and posted on Instagram. Hell, Barnett uses it as his avatar on Twitter, and Freddy contacted me about getting him some shirts. I decided to throw some up for sale and raise some money for Roswell too. I think it's a cool movement that is only meant for the best of intentions.
PS- www.brandedbuffalo.com is where you can see the poster that I created. Also working on getting more "Buffalo" themed stuff up.
