Yes, I am very familiar with the trip between Northbridge and Lewiston. I make that very same trip every Friday night and back to MASS again on Monday mornings. Not to Lewiston exactly, I get off exit #63 in Gray, ME and and take 26N into Oxford,ME. I'm building a retirement home in Otisfield, ME (a ways off Rte 121). I just took another close look at my back tire and as much as I enjoy the ride, I can't risk another trip on that tire and I can't justify putting a new on so it can sit on it thru the winter. I'm also very familiar with Rte 121 into Auburn/Lewiston (lumber purchases). I just read in one post by brtn15 that he is in Bar Mills, that puts me between you two (but closer to Lewiston).. Maybe we can meet up next year after mud season passes.
