Spring and summer skitter bites - normal - black flies in Sept. mostly - nasty but bit of swelling and itch, that's it.
Bears not a problem around here, but with the bugs, one usually doesn't go into the bush in the summer time unless slathered in 95% Deet. I'm allergic to the stuff now, and have to put up with the less effective over sprays.

Thermacell machines work very well most of the time and the sprays are not necessary. Just carry extra butane and pads. good for about 3 1/2 hours though, per pad and 4 pads per butane tank. Lops onto a belt, check often to ensure still running. These are all we need for bugs when shooting the rendezvous trail walk. We do have some bears, but rarely see them.
No grizzlies this close to town, but possible to run into one once out of town. I never have, but friend of mine used to see one or 2 every hike he took with his new bride. She was getting the idea there were grizzlies all around us. Just lucky, I guess. Keith usually had a .45 ML with him, loaded with round ball. LOL, or a .22 for protection. Griz. weren't interested in them, of course. Black bears can be much more problematic.

They are likely 100 times more dangerous. With fewer people hunting them these days, there are some big ones out and about. I always pick up a tag, just in case I see a 7 footer. They, and the newly spanked 3 yr. olds are the most dangerous.

Lots of ticks here too, apparently. some have Lyme disease - more of that recently in the last 10 years or so.
