Guide to Camping in the backyard
    Camping in your backyard is full of fun, whatever your age. It's great for keeping us relaxed. It offers chances to check the night sky and to be noisier than usual. It lets us have friends over to stay who might not fit inside the house! Follow these instructions and you'll have a night you'll never forget!
 
Depending on the number of family members and guests, you may need more than one tent. Tell your friends to bring their tents if needed. Follow the instructions or check out the articles on how to put up a tent on the Internet.
   
You'll want your guests to be able to relax in comfort. Put something soft to lie on the floor: A blow-up air mattress or thick comforters may work well. Fill the tent with soft toys and  blankets (毯子). Have lightweight sleeping bags or cotton blankets. They are especially important if you live where the night temperatures drop greatly.
       
    If you have a picnic table, that would work best. If not, set up a few chairs and a small table to set out drinks and food. A simple choice is to lay out a blanket in the sun, so that your friends can eat and talk. Be sure the grass isn't wet!
      
    Family camping can be lots of fun, but if you are not prepared for some pests to watch for, it can be an unpleasant experience. Flies and Mosquitoes can quickly bring an end to your comfort around the campground, so take along something that helps keep them away. As a general rule, avoid all snakes in the outdoors.
         
    Plan some activities. You're camping in the backyard, so it's time to make the most of being outdoors. Have a camera nearby to take silly photos of you, your family members, and your friends. Take one large group shot with everyone smiling and laughing. Be sure to make copies for everyone!
