We are headed for Yosemite, leaving on Wednesday, and coming back on Monday. Hopefully I'll have Internet, so I can continue to post.

No, we don't expect snow, but wanted to be prepared just in case. These are the first chains I've put on. Yesterday, I was one grumpy
fellow. I had ordered chains online, and they were supposed to be for my tire size, but I tried getting them on for two hours, in vain.
My hands (even though I wore gloves) will hurt for days to come. I finally gave up and decided it couldn't be that hard. So I went to
the local Pepboys, picked up a pair there (I was surprised to find them locally), and voila, no problem. Guys' rite of passage, I guess. :-)
