Idaho Hunting Tags and Fishing Licences Are Disappearing
This is no joke, hunters and anglers in Idaho are dealing with disappearing tags and licenses. No they are not being stolen, the ink is just going away...
How could this happen? Well according to sources there is an issue with heat sensitive paper. I was reading an article by AP on the Idaho Statesman website, and it said the old disappearing ink routine apparently caused by faulty heat-sensitive paper.
Don't worry if this happens to you as you can get a replacement for free, now if you don't catch it before you go hunting and have to notch your tag I am not sure exactly what the protocol would be there. It's obviously more prone to disappearing if they are kept in warm places. Most of the time that may be the case so check tags and licenses just to be safe.
