I wouldn't worry too much about getting from campground to trail on the non-plated bike. The local law enforcement in that town is pretty lenient, as long as you're not being obnoxious. Is it a four stroke with mild exhaust? Shouldn't be a problem. Two-smokers and loud mufflers might attract too much attention, and so does recklessness on the street. Don't speed down mainstreet (they enforce speed limits), keep both wheels on the ground 'til after the pavement ends, and you should be fine.
