It's a good idea to set off on a camping excursion with a couple of camp stoves. While you might have a large, propane-powered stove with multiple burners to do the bulk of your cooking, a small, collapsible camp stove can also be a good product to carry. These stoves use twigs as fuel, rather than propane. The small size of this device means that you won't likely plan to do the bulk of your cooking with it, but it can certainly come in handy when the need arises.
When you're preparing to go camping, one of the things that you need to think about is how you'll minimize your chance of an encounter with a wild animal. A run-in with a wild animal, particularly if it's aggressive, has the potential to damage your camping gear and potentially even cause an injury to members of your group. Fortunately, there are a lot of different animal deterrent products on the market that you can buy in advance of your trip and pack with your gear.
