Camping Trip Planner There's nothing worse than being 4 hours away from home only to realize that you've forgotten something important. This has a pre-loaded inventory of all the things you could possibly need for a foray into the wild. You can tailor the lists to reflect the kind of equipment you need for your trip, and check things off as you pack them.
