My perspective is that for the most part the boating was not as normal, meaning that there were less power boats than normal, But there were loads more kayaks and canoes, at least in the Alton Bay area. In my travels from CT it seemed that once I hit the Epsom or Epping ( I cannot keep them streight) traffic picked up, but slowed down. Seems that there were a lot of leaf peakers at 10 PM then during the day. (slowpokes)
It seemed to me that people wise the southern part of the lake was always busy, but the boat traffic was not that much until last weekend.
