Urgh, posting this a bit late I know.
If anyone is attending SPWF this weekend (which I'm sure is almost no one because you're all going to be at KR right? RIGHT?), bring a few bucks along to donate to the RESCU foundation, a not-for-profit that provides healthcare assistance to Renaissance Fair workers.
Wait, did I say donate? Because what I meant was "buy some cool bits", because in order to raise money RESCUs representative will be selling donated items gathered from the community. Items available range from costuming and props to old electronics ad household knicknacks: you may be surprised what you can find!
So if you're walking around the dealers room, look for this guy. Give him money.
Oh, and tell him I said he's ugly.
