Summer in Wellesley is a great time to get out and hike the town’s trails. I’d always been curious about that Overbrook Reservation sign at the corner of Route 9 and Weston Rd., so I decided to see what that area, purchased in 1978 by the Town Conservation Commission, was all about. A trail guide I consulted suggested that I could hike along Boulder Brook via a narrow, rough trail at the bottom of a rocky bank. I found the general area easily enough, and Boulder Brook was there alright, but if there ever was a trail in that 10-acre wetland area, it’s long since been taken back by nature. So don’t go there. That’s why you have me, to warn you off such nonsense.
