Hmm, the sling pictured was found with the last two spiders. There were quite a few slings, I took the lid off of an old trash can and they went everywhere.
Th obvious S. Grossa's I'm finding are in my basement.. and my brother's house (his arachnophobic self called me going "I have black widows!" wanting me to come save him.. I think he about died when I let it crawl on me)
