I used to mountain bike, but not nearly as serious as you guys were. I am more into backpacking. I have made many trips to the High Sierras near Lake Tahoe. I have been out for days at a time without seeing a single person not in my group. The longest trip I have been on so far has been 8 days, and we covered about 75 miles. If my leg heals soon enough this summer I will take a trip up there in mid-august.
