Thanks for all the great info everyone. We'll be printing this out and bringing it with us to refer back to as we play it by ear. Were 'staying' with a group of friends who are renting a condo
so we want to be reasonably close. A campground where we can have everyone over for a campfire with bathroom facilities nearby would be our first choice (next to a lake with fish so thick and hungry you get bored with the monotony of pulling them in would be a nice bonus
). Summer being what it is, we'll take what we can get.
I'll be hitting REI and the bookstore tomorrow, any specific topo maps or forest service maps, other than general Mammoth, Eastern Sieras area I should keep an eye out for? I was looking through my copy of Backcountry Adventures, but my copy is for the Southern California region and cuts off just at the edges of where I'm researching. I'll be putting in an Amazon order for the book on the Northern region; both will have a prominent spot on the Sportmobile's bookshelf.
When the little ones get older, I want to tell them we have a three day weekend coming up: Here's a map, find someplace within an x-mile radius from home...
