Yes! I was the guy taking off the knee brace next to the ancient Kelty frame pack (which is the most comfortable pack I've ever carried). Only, we weren't fishing. Just hanging out. I remember a hiker (you, probably) who headed down into the Pemi. How about that?
I suspect you were moving faster than we were (on account of me, mostly) and that explains why you didn't notice the bugs as much. Also, one of my buddies is birder and he often stopped to listen for birds. I should have noted that we first started noticing the bugs when we stopped for lunch #1 at the base of the cascades and as normal, the black flies were worse closer to the water. Had you stopped by the Pond, I suspect you, like us, would have noticed the black flies. We were swarmed but it was manageable with head nets. Same thing climbing Nancy. Things were fine if we were moving. But we got swarmed when we stopped.
