I broke my seat post (single bolt - it's what broke) yesterday while on the conservation land. Rode out to Foxboro Bike on 140 and I got hooked up with exactly the same post I was riding (an 11 year old Trek system 2 post). Ordered a new Bontrager post through them as well. I think the guy running the shop's name is Ryan, he's a good guy. Stop by there if you're in town and need something before a ride.
