Well...if your first goal is imbibing, you might end up with a stomache-ache!
Awesome trip to take on. First question - are you in condition to take on a long ride or three? My first tour - 145 over 2 days - I overestimated my condition. By the end of the first day - 75 miles - I was toast. The second day was not fun (massive understatement). If I could do it again, I would break it up into 3 days, slow down and enjoy being out and about.
Take more pictures.
Find a way to have a cold beer at the end of the day.
Cheers and good luck!! I envy your ride!
