Hi Ryan and welcome to bass-n-tubes.

Yes you are welcome to come join us at whites on Sept 8, and in October as well without any club dues being paid.
There are some rules and regulations that you should be aware of. You can read those here on the forum as well. Mostly basic stuff, fish size, quantity, livewell regs, and a few basic rules.
The only thing I can think of off that will be necessary to have prior to fishing a tourney would be a livewell.

Feel free to ask any questions, for the most part they will get answered. Look forward to meeting you.

Taylor
