Hope I don't in trouble for this, some boards have issues referring to other boards but this is a kick butt place for .gpx files and places to go. Dude has been everywhere:
Coyote Flat is supposed to be nice.
Inyo NF - Coyote Flat
Laurel Lakes run at the bottom of the road to Mammoth is nice but 4wd is not needed for that run. Think there is fishing back there too. This place is AWESOME... even had a waterfall while we were there.
Inyo NF - 28E201 Laurel Lakes
Inyo NF - 30E302 Wheeler Crest
Keep searching on Inyo Forest and White Mountains.
Surf the site... Join the boards as good people over there.
Guide to Northern Cali Backroads items 32-43 should keep you busy. Load the way points into google earth to see where they go & if you are interested in going. I'd stay away from Bodie this time of yr. HOT, DANG HOT!
