I mail mine in every year by snail mail. As of last year they started sending multiple sheets to fill out because they want them mailed at the end of each month I believe- regardless of if you caught any or not.
Yup ^^ ... It used to be end of season but as of last year they now want info mailed back by the 15th of following month. I wish they did it electronically but no, have to mail it in.
I have been doing the net thing for years and Never been asked to see permit once. I just know the one year i decide not to renew it, i'll get checked ... Not worth a fine when permit is only ONE dollar.
