Don't feed the animals. The raccoons here are very camper-savvy. Put your food in your car if you want it to be around the following morning.
Take out what you take in.
Don't hike at night, and camp only in designated areas.
Even though Shades is not a very "deep country" park, it's always good to let a friend or family member know you are going hiking, so they can get worried if anything happens to you!
Use common sense. Any experienced park-lovers know what to do!
