I Noticed that with the pronghorn tag. I assume since everything is online now all tags are associated with the number on your license and the warden can log in and see everything you have or don't have
I am guessing the same as the youth deer tags, if so...they were kind of a bugger to get separated from the backing paper.
Otherwise, it's a good call on NDGF's behalf. There were years where I had to carry at least two certificates because of the number of required stamps that needed to be signed and affixed to the back of the certificate.
hmmm... i totally forgot about that extra part anyways. can't remember the last time i pulled it off and put it on my certificate. probably stopped doing in when we used to get like 12 tags each and then never remembert to start doing it again.
