Thanks for the reply, John and thanks much for your patience, this is all new to me. If the passes in the Sierras, Cedar Breaks and the Rockies are snowed in in mid-late April and Early May is there way to get around them? You suggested going north to Lewis and Clark and the NT and litespeed suggested the southern route. Since I have to get to DC by June 10th or so I am willing to hitch a ride/Amtrak etc around these impediments.
Having said this, is there a way or have you heard of a way to rejoin the TA at Pueblo, CO via these alternates:
SF, CA - Bend, OR - Missoula, MT - Pueblo, CO (Approx 2100 mi)
or SF, CA - Phoenix, AZ - Pueblo, CO (Approx 1600 mi)
Sorry for these amateur questions, there may not be a straighforward bike route using the cities I cited. Any help would be greatly appreciated.
