I first found these maps when I was at a motorcycle shop and picking up a helmet buckle. I thought it was perfect to store in bags when I was out on the road for a day trip with my bike. Later I realized these were the kind of maps you needed to have when you were travelling across a state or a two. They are so durable they last forever and can be tucked into a pocket behind a seat, a saddlebag or the slot in a door or between seat and console. I have navigation devices everywhere - phone, truck, bike, etc. However, I've found that a hard copy map where you can spread out and look at the big picture is necessary when considering alternate routes, distances between stops as well as final destinations. I've used the computer to plan trips but the tools for trip planning are still limited and difficult when deciding where to stop for gas, sleeping or simply for a break. When you're on the trip those same issues can arise and trying to fumble through the commands while considering remaining fuel can be difficult. What is nice about these laminated maps besides their durability - my first one is over 10 years old, is their easy fold ability. My wife tends to fold them forwards and backwards along the seams. I fear they will crack and break but so far they've held up. She likes to fold them into a quarter page size for handling and studying where we are and where we're going. I have a complete set for every state west of continental divide. I got Idaho, Montana/Wyoming to finish the set and because I have a trip planned for that area this year.
