Depends on the campground. Been to Maine and Virginia where they allowed us to ride our street bike in and out, parking it on site. One Va place charged us $3 per nite extra because we had an "extra" vehicle and the following year they wantedf $5 a nite. Found another place to stay after that. In Myrtle Beach they won't let you ride in, but have a designated spot at the entrance to park bikes. So I end up paying extra for a beachfront site, then have to leave the bike 1/2 mile away and walk back and forth whenever I want to go somewhere (not like I don't need the exercise, but seriously
???). And I always have to go back after it cools down to cover it. They say it is because some permanent residents complain about the noise. So all of the kids on golf carts with boom boxes blaring are MUCH quieter
. Of course during bike week thay allow them to ride in and out, because they want to rent as many sites as they can. What a joke.
