I asked the same question to a touring PRO last year.
His answer was-- Hell yes. Who do you think I am KVD.

I have always wondered the same thing. I�m just not sure if these people don�t read the responses or if they just want to impress themselves.

I don�t think so.

I did some research and found out that you do need a fishing license for every state you fish in.

what ?

Are you sure about that???

They are supposed to but don't always http://www.bassfan.com/insider_article.asp?id=139

I didn't read all the responses, so if no one said it, the answer is Yes. They are checked at registration and have to show insurance, registration and a valid license.

Is it also a yes for non-pro's, or are we just talking pros? Can I get a few yes's for non-pros too?

Here is a link that will clear it all up

If they are over 65,is it true they don�t need a liscense in OK?

they don't check registration or insurance at tourney registration. They check a few random boats at launch. ....at least that's how it was when I fished pro level events. Maybe it's different this year.

They are required to have valid license, that doesn�t mean they always do. My experience in Louisiana is most do, especially BASS events. I have seen fileboxes pulled out with numerous states accounted for. Other instances no licenses, registration or paperwork period. I know for fact one of the Fisherman that had picture on Kelloggs box was cited in pool 4 of Red River for no licenses.
