I'm gonna do this. I just bought a train ticket to Denver to arrive Sept 2.
I'm guessing my 40* bag isn't going to cut it, especially towards the beginning of Oct in the San Juans. I'll just have to order a 20* bag and be done with it.
The train arrives in Denver about 8 AM, so I need to decide if I want to head right to the trail and hike 9 miles or spent the night in town and get some sleep first. After 3 days of traveling (over night bus to NYC, then 2 nights on the train), I'll probably be a zombie by the time I arrive. Denver must have a youth hostel to stay at.
