Has anyone found anything that keeps the gnats away? I tried everything I can think of to keep them away and nothing works for more than a couple of minutes. People keep telling me skin-so-soft works but I tried it and it didn't faze them. Cigarette smoke knocks them back but a guy can't smoke constantly. I'm about to decide a head net might be the way to go. If anyone has found something that works please let me know as those things are putting a real damper on the fishing.
