The beam cabled to the shore technique is used a few places in BSP with good result. In some spots two beams meeting on a rock midstream that just need to be set back on the rock if flood knocks them off. I know another spot in NH that uses that technique but won't say where because I think the rules say it shouldn't be there.
Did they clean up better when they took out the Thoreau Falls bridge pb? My last trip there was in '19 and I happened to catch them as they were winching the stringers to one side. Stopped going there because it got too crowded for me, not because they took the bridge out. I was starting to meet people out there which always seemed odd after years of going there to be alone. Will be headed through there this June, but thinking I will head up Shoal Pond to avoid trying the TFalls crossing. That trail still exists, right?
