Touring to speak about sex worker rights

I'm currently on tour from coast to coast, speaking to various groups about why it's so vitally important that governments stop persecuting sex workers and denying them basic legal sex worker rights.  And though I'm selling copies of my book along the way, hotels, gasoline and other expenses are eating up my budget pretty quickly, so I need your help.  The tour is costing me about $350 per city, and I'll be visiting 26 cities in all; that's roughly $9000 total, and I'd like your help to raise it.
