The event takes place on Sunday, August 9th, and registration is from 11:00am till 3:00pm, at Toolbox Tattooz at 32 Yonkers Avenue in Yonkers, NY. There is a phone number below for info. Tix prices seem reasonable, and it looks like a fun day.
I think the basic gist of this fundraiser is to ride your bike to various pick-up points, get your poker card while there, and eventually land somewhere and play the hand you get dealt. There will be prizes, food, entertainment, and 100% of the funds raised goes to the Yonkers Animal Shelter, which honestly needs funds.
So, if you can be there, or pass this around, please do. It's being put together by a dedicated staff person who, I've heard, has personally rescued many of the dogs at the shelter and makes sure they are looked after.
