Wednesday June 10 - Walk out of house, board trolley, transfer to subway to Boston bus station, board bus to Brunswick, Maine.
Arrive in Brunswick, walk about 7 minutes to Center Street Cycles (excellent shop!), rent bike, ride in weekly Ice Cream Ride organized by local cycling club, then to dinner and motel.
Thursday June 11 - Ride from Brunswick to Popham Beach, approx 55 miles r/t.
Friday June 12 - Ride south from Brunswick along coast to Mere Point, approx 25 miles r/t, return bike, walk to bus station, bus back to Boston, subway/trolley back home.
Total minutes in car: 0.
Could have easily spent several more days riding in this scenic and interesting area without repeating routes.
Also had option of riding my own bike to Boston Amtrak station (approx 30 minutes, mostly on MUP), putting bike on train, and going up to Brunswick that way. Easy as pie!
