I have been planning to use both a tent and shelters along the trail. Up 'till now I didn't even think about bug issues.
With a tent this is not an issue, but when staying in shelters, I have to assume they can become quite annoying. Seems like a waste to bring along some sort of bug net that I don't need when using the tent. Maybe I should just switch to a tarp err... I mean Hammock.
Assuming a NB trip, when will we begin to run into annoying bugs (biting flies and mosquitos)? I wouldn't think until mid-to-late May. But June, July and August are probably going to suck.
