We mounted ours on the front window and only put on the stickers for the states in which we have actually slept in the trailer in the state. Before she knew the criteria, our daughter was trying to figure out how we got from NV to WY and from NC to AL.
We picked it up at a RV dealer/repair shop in Grand Island, NE while bringing Big Ei from CA to VA. We didn't get the Canada map at the time as we had only been in BC.
We got a little inspired when our neighbor at the Silver Star RV Park in Vernon, BC shared his travel map with us. He (85) and his wife (xx), out of Red Deer, Alberta, travel every summer with a pick-up and 5th wheel and have covered almost every road in Alberta and BC. We got to share their joy when they got the good news that their newest great grandchild was born.
You just never know who your neighbor might be and what memories you will make when you are camping.
