I think they post their trips on the trip planner thing on the AMC site. It's very confusing to use, which is why the bike committee doesn't use it... could you switch your membership to the Boston Chapter? That way, you would get the MUD, which is a little more up to date than Outdoors, because the publication deadline is a month later than Outdoors. I've heard the HB trips fill up really fast. If you need a contact, you could try to email Chuck Cafarella. He used to be the chair of the bike committee and now he is very active in HB; tell him you are an aquaintance of mine. Also, the Boston YM group does lots of hikes.

Good luck!
