That reminds me of a trip my son and I took to the BWCA in 2021 when the border was closed and we could not get to Quetico. We were paddling across Iron lake, coming back from Curtain falls and came upon a group of girls/scouts, 4 canoes.  Every one of the occupants were wearing bug head nets as they paddled across the lake.  We exchanged hellos as we passed by.  As soon as we got out of sound range, my son and I start cracking up.  There was not a bug in sight out on the lake, but you can't be too careful I guess. It was a warm day too, so that could not have been too pleasant.  You see some strange stuff out there sometimes.
