Portland, ME to Providence, RI end of August

Looking for up to 3 other adventurous folks to join my one-week bike tour from Portland, Maine down to Providence, Rhode Island the last week of August. I do my tours self supported, camping most nights, but maybe a night or two of Warmshowers as well where hosts can be found along the way.

My plan is generally 45-50 miles per day, with a total of about 290 miles in the six (or perhaps seven) days of riding. I want to hug the coast, which means more roads instead of just the Greenway, but I find that so much more fun, riding through the small towns.

I am 61, male, and have toured off and on for almost 30 years. I would be taking Amtrak up from Washington DC (where I live) and then back home at the end of the trip.
