I have a very good friend who lives in the Boston area, and is looking to kick himself back into shape. He's a big guy, and right now doesn't want to invest in a new bike but would rather start out on his old one. It's an older (early '00s) Trek 820 MTB.
Now his problem is that he wants a bike shop that isn't going to be... well.. snooty . He wants to throw some slicks on the 820, get some help getting it fitted to him, and have it tuned up properly. I'm sure (knowing this particular person..) that if he likes it, he'll end up getting something a little more "fun".
Anyway, need recommendations. I know the legendary Harris Cyclery is in the Boston area, but from looking at their website he felt a bit daunted.
