Bought my fishing license on line and then was trying to figure what I needed to carry. I know I can print it and carry the paper, but was hoping for some type of mobile app that I could use as proof. I didn't find a DNR app for the iphone, but I was able to save the e-license link which shows the purchase. Would this be valid if stopped? My intent was to cut down on the things I carry in my wallet, but am not sure they are there yet with the application. Thoughts?
