I too think of Soyo when I hear Southern Sierra, but I don't necessarily the other way around. I thought of fitting in some of the sort of close areas like Courtright, Tollhouse, Wishon, etc. in since they are kinda close, but in regards to all of the So Sierra it seems like such a much bigger subject it should have it's own site. A So Sierra subforum could easily be split off into a separate site someday at a later time too.
Any input on this out there?
