Always Pack Lots of Plastic Bags

When you travel, go camping, or even walk around on a college campus, always pack a plastic bag in the bottom of your suitcase, backpack, or duffle bag. These can be used for shoes, dirty clothes, toiletry bottles, or souvenirs that you don't want to get wet for some reason in your luggage. Having multiple bags on hand always ensures you'll have a place for everything, and if you get caught in a rainstorm, you'll have waterproofing material immediately on hand!
