The Chances

5 days 'til Half Dome. Here's an interesting bit of info: 100 Classic Hikes in Northern California calls the Half Dome hike "The Burn".

I went to REI last night and picked up some National Geographic topos for Yosemite SW (which includes HD) and the Tahoe Basin (for the Tahoe Rim Trail). They're pretty nice maps, but cost $10 apiece. They're pretty sturdy and should hold up to repeated abuses on the trail.
