Look after your maps Do you need a map to find your road maps? Keep them filed alphabetically by state in a folder or three-ring binder. Then, when you begin a trip, you can easily find the map you need. Folding it up again, however, might not be so easy.
Bad weather If you plan to go for a hike - or just a leisurely stroll - while on vacation, pack your maps in a large zip-lock bag. That way, if it rains, your map won't get soggy and hard to read.
Write on your maps Buy a disappearing-ink marker pen from your local fabric store. Use the pen to trace your route on your map. In a few days, the marks will fade away, and you'll be able to reuse the map for your next trip.
