People like to dress their sled up, add something different, support a certain cause i.e. business, charity, club.....
Look at those that wrap a sled, some are quite extensive & some are quite small - Or you have POO who has given the rider so many choices to customize your sled from the factory with all the colour options, just to be more personalized.
Some are into it and some are not - good to have options.
Same for the license sticker - I try to remove the old before applying the new one in the same spot.
I find WD40 has worked better for me though - spray a rag, let it sit on sticker and then remove residue.
The whole idea of using one of these to transfer a permit, I get it, people will always make poor choices, you cannot stop stupid.....I would like to think the number of people that sled and would consider this, are just a "fringe minority".....lol.
