My understanding, which is the result of a very quick Google search and Phil could 'fill' in allot more accurate info no doubt, is that in Maine you have to attach a transportation tag to get the to the check station to check your turkey where they issue you a permanent tag.
Because you don't have to go to a check station this season there is not a transportation tag needed either.
But they still require a turkey permit and still have bag limits.
