I'm in the process of planning a road trip to Idaho this summer, and in my search for trails I've discovered that many of them are designated as "open to motorcycles" from June through September. I have found some great rivers that I want to fish, but I hate the idea of hiking along peacefully only to be interrupted by the loud buzzing of a dirt bike. That said, I also know that just because a trail is open to motorbikes doesn't mean they're on it every day of the week. Anyone have experience with this? Is it even something I should worry about if the trail isn't within spitting distance of a major town?
