Haven't posted in forever but thought I would add just some info to this thread... Hunting on Penobscot Indian Land is allowed 7 days per week- I am not sure of the other tribal lands in Maine but believe they follow the same guidelines. For Penobscots the actual season dates are available through the tribal website but for big game the firearm season runs September through 12/31. I do not know of any caches that fall within Penobscot Tribal lands however do know that there are a few active caches that are very close if not within Passamaquoddy Tribal land. Feel free to contact me if you have questions.
