I've always assumed any one showing up alone is alone for a reason.
If none of there "friends" wanted to climb with them than neither do I.

i almost never had a partner when i would head down to the red on the weekends but usually i met up with people at Miguels. If that wasn't the case I could usually show up at a popular crag and bump into people that I knew on some level who would offer for me to join them. always bring my own rope and gear though, and let it get shared around (im easy like that)
Sand inhibits the production of toughtosterone, so get it out and send.
