If the campground is getting too crowded, you may think it would be nice to set up your tent outside the designated camping area to give everyone a little more room and privacy.

Hiking is a popular (and fun) thing to do when camping, and if you're in a popular state or national park, the trails will probably be full of people.

Pets are welcome at many cabins and campsites, including some in National Parks. This can be a great way for you and your dog to spend time together.

Leaving food out could bring in birds, mice, raccoons, bugs, and other pests that can be annoying. If you live in bear country, this could be very dangerous if you bring in the wrong kind of visitor.
