I will never put my number on my vehicle again, I do some Outfitting/guideing up here and had my buisness info on my truck, I was out hunting on my own for whitetail, got to the land I had permission on and parked my truck on the side of the road and went for a walk. When I got home that night, I got a call from a fish and wildlife officer saying a landowner had called in with my info, and I was illegally Outfitting/Guideing on his land. Turns out it was the guy who owned the land on the opposite side of the road to where I was walking. Just a headache I dont need.
I have been thinking about getting door magnets made up, then I can take them on/off when I want to.
