WTF is going on with GW these days? They get some TV shows and now they are out there doing investigations on everyone and thinking that they are FBI or something.
Then they like to issue citations on stuff done years ago. If we all got speeding tickets for what we did last year, would sure piss us off.
For OP - where is the address on your driver's license? That's what this all comes down to. You claim residency somewhere and that's where you buy Rez hunting/fishing licenses.
It aint rocket scientist. And the GW will probably get a raise for tracking you down.
