If you're a wilderness medicine geek, here's a site you'll love: http://spiders.ucr.edu/. There's a lot of myth and lore about venemous spiders out there, and this site aims to set things straight. This article, and its accompanying map, about brown recluse spiders and bites, are probably the most interesting bits. The site also bebunks the daddy-longlegs juggernaut, once and for all.
