I ran into gnats just north of the Smokies. They are more of an issue during the day while hiking; beyond annoying!
Got a couple of months off from bugs, then found some overly friendly mosquitoes in NY.
What did you have to use?
What did you use that you found most effective?
In some mysterious way woods have never
seemed to me to be static things.
In physical terms, I move through them;
yet in metaphysical ones,
they seem to move through me. - John Fowles
