Oh boy, I can't wait to read your report! I have forwarded it on to my DH, as he is considering doing the Northern Tier next summer if his body holds up! He just turned 60 this week, and riding cross-country has been a dream of his for as long as I can remember.
If he does it, I will be traveling along with our dog and riding when I want (like when I get to our nightly stop, riding back to meet up with him). I did this when he rode the Katy Trail this fall, and it worked out pretty well. I am not sure my body (pelvic fracture in '05) would allow me to ride the entire thing, and since we have Paisley, we think this would be the best way for us to allow him to make his dream come true.
Congratulations on your accomplishment and thanks for posting!
