Instead of getting food for themselves, these animals and birds will take the easy way out and hang out at the campsites for handouts. It's pathetic and sad. Leave your campsite cleaner than when you came. Make sure every gum wrapper, twisty, etc. is picked up. Respect your fellow campers.
Many campers like to stay up around the campfire at night and talk.
That's fine, but remember to keep the voices and music down. Camping is as individual and diverse as the people who do it. The only rules that apply are the simple ones that I mentioned above.
