winter climbing (living)

I'm planning my next winter and trying to post up somwhere with good climbing. Any suggestions on a good place to spend multiple months living and climbing (cheap)?

How is the winter at Smith Rocks, or Bishop? Not if they have some good days... but if you can live and climb reguarly in either?

any other smaller/lesser known areas? anything far into the southwest?

What's the longest you have spent in el potrero chico? What was that experience like? What does food cost?

Thanks
