Maine's deer season gets underway tomorrow, October 31st. If you're going into any wooded area, assume there are hunters present and wear at least one article of hunter orange. A hat and a vest is even better.
And hunters have as much right as geocachers to be in the woods so avoid confrontations and given them their space. I hunt but I'm also aware that there's a small percentage of deer hunters that are inconsiderate goobers that think getting a buck is more important then life itself. Avoiding any type of contact with those "hunters" is a good idea!
Be safe, have fun, it will be done the second Saturday in December, the official end of muzzleloading.
