Not that I know anything about it, of course - BUT, if you happen to be traveling up Route 3/11 from the outlets in Tilton, and you turn right onto Silver Lake Rd., you will come to a set of train tracks. There's a dirt lot on the right where one
might park to avoid parking right next to where one
might be jumping off a bridge in broad daylight. If you were to cross the street from where you parked and walked the tracks, in about 300 yards you
might find yourself on the top of a really great bridge to jump from.
I've "heard" that the water is deep. I've also "heard" you should bring a pair of old shoes, as the climb back up to the top of the bridge is a little rocky. But I really don't know much about it.
