I'm going to Yosemite in July from Vogelsang to Lambert Dome.
Previously I've backpacked from White Wolf to Tuolumne Meadows and loved it – except when a big rattlesnake crossed my path along lower Tuolumne Creek. The two black bears on the trail didn't bother me but that snake passed JUST behind me. Probably could have bitten me as I unknowlingly passed it if it had been in a bad mood.
