I always had the problem of forgetting my license when you only had the one little piece of paper. If I remembered to look for it I could not find it. Was it in my hunting back pack, on my fishing vest, in my trout bag, on the boat somewhere, etc.
Now with online licensing I just print out a dozen copies and keep one copy everywhere I need one. One in the wallet, one on the boat, one in my hunting crap, one in the car, etc. Online licensing is the best thing that happened to sports folks.
