I'll let you in on a little secret - Dusky "Crab" Cakes are really made from spider legs!  I know it's a bit disgusting, but the cakes have a nice, tangy flavor and make great snacks!  Bring me Gooey Spider Legs and I'll whip you up a few of them.$B$BI hear Venom Web Spiders are a good source - they nest to the north, between the foothills and the river.
