I was pedaling around Adams Woods, not a mtb hot spot, but convenient for me, and from everything I can understand it is open to mountain biking. However, there's one section of single track near the end of Fairhaven road that has a sign that reads, "No Bikes. Unsafe for Horses." It does not appear to be the same type of sign that appears in other areas of Adams Woods. Does it mean that horses can ride there but it's not recommended? It goes near some houses so I'm wondering if a home owner decided to just put it up on there own. Anyone know what the deal is? Thanks.
