I would also advise wearing orange and making a lot of noise. There are intelligent hunters, but they won't be anywhere near a well-traveled bike path, especially on a weekend. So, you can probably count on running into the idiots. Put it this way: you can buy gasoline, beer, and ammo in one location (at least where I've lived). Not exactly ingredients for a MENSA meeting! Serious hunters will come down hard on these guys because it gives all hunters a bad rep, so I'd put out the word in the hunting community (gunshops will know) as well as the biking community. Share the woods.
