While camping is an opportunity to get away from city life, city problems find their way into campgrounds. No campsite is completely protected. Being in a tent leaves you vulnerable—the tragic shooting of a father at Malibu Creek State Park while tent camping with his young daughters is the most recent example.

This and other incidents won’t stop those who love to camp, however. Camping is growing in popularity in the U.S. According to the 2016 American Camper Report, 40 million Americans went camping at least once in 2015, with tents being the most popular type of shelter. Here are some suggestions to keep your belongings safe while camping.

Leave Expensive Items At Home. Camping is an opportunity to unplug. Do without electronic devises and expensive jewelry when camping.

Carry Valuables With You. Whenever you leave the campsite, place your wallet, cash and cell phone in a backpack or fanny pack so you can take the items with you.

Lock Up. If you must leave valuables behind, put them in your locked car out of view. Large items such as water toys, coolers and bicycles can be attached to trees, RVs or cars using a lockable, heavy-duty cable.

Get To Know Your Neighbors. A friendly greeting to a neighboring camper is a good idea—both of you can watch out for one another.

Set Up A Mobile Security System. Purchase portable, inexpensive motion sensors that will alert you to tent intruders. Place them just inside the tent opening. That way, the alarms won’t go off if an animal happens to pass by.

Know Who To Contact. If an incident occurs, report it immediately to security personnel. If you are camping in a designated campsite where people must check in and out at a security gate, odds are good that the culprit is a fellow camper.
