Ok so to print out the form to mail in for your license go here:

It's a pdf print it and mail it in. Check is made out to DEP per DEP office.

I went to the post office bought a money order and a stamp
I am keeping that in my wallet as proof and going fishing TODAY.

If I get questioned I will provide proof. I hope I get questioned
and ticketed so I can take this to the highest court of the land.
