Just to clarify, you still have to follow the land management rules for travel. Most prohibit off trail travel, and many smaller roads or trails have seasonal closures and/or are only open to certain types of vehicles (motorcycles but not atv for example). The IDFG motorized restriction units tighten that up even further, by limiting access to roads open to full size vehicles only., albeit with some fairly vague definitions of what that means. You can only use motorcycle/atv trails to access camp and yes, to retrieve game. But ONLY if these trails are otherwise open.
Congrats to the OP and thanks for sharing the pic! I make the assumption you know the rules and followed them. It??s just an important issue with me that we all do.
