We spent 2+ years traveling the US in our trailer visiting every national park, monument, historic sight we could. We haven’t seen them all, but we’re also not done. We have a beautiful, but old, National Park Map that ended up with pins & handwritten names of all the places not on it. We decided it was time for a new map. No one does this better than National Geographic and we couldn’t be happier with our purchase. It’s beautiful and extremely detailed. It will take some time to transfer all the pins, but here’s a picture.
