There are rvers and people who own campers. You know the guy pulling a 30 foot tt with a toyota 4 cyl. They are almost everywhere. We have noce county parks and during the high season you have to deal with them. Cutting through the sites, up until all hours screaming and cursing. Its all about them and not the surrounding people. Some parks take security seriously, others do not. Like others say, holiday weekends im parked in my driveway. During the high season we check in early in the week and enjoy the quiet then only have one weekend to endure.
