I gave a GPS but would like a way to hold a 3x5 or 5x7 card to the tank. Going down the Blue Ridge parkway in 3 weeks and wanted to list various mile posts and which ones have gas, food, etc. Thought about getting one of the plastic folders at an office supply store and glue some magnets on the inside but am concerned about scratching the tank. Seems like the top coat on my Ultra is so thin if you brush against it you have scratched through the color. All the map bags I can find are too big and cost more then I want to spend. Any suggests or has somone made their own?
