In reply to Hamad:
If you stay at the hostel California you can borrow pads, otherwise you can hire from the shops in town.
I didn't go to Owens, although a bunch of people staying at the hostel did. I thought about it but figured I had world class bouldering or OK sport climbing to do and figured why fly across the Atlantic for anything but the best. I gather it's easier on the skin though which might be a consideration.
As for partners, you can probably just float around the boulders and join in with people if you're the social type, everyone was very friendly; other than that I suspect the coffee shop, the hostel or the campsite are the best bet. Toms place is a way out of town isn't it?
