Cowboy division hasn't pulled 200 boats for an event in the last 5 years that I can remember, so you're probably safe, signed up with out the coangler, but you can get one for the rest of the season by just asking around at the first pretournament meeting. Ask the tournament director and he'll help you find one.
As for me, I'm out this season, but may jack pot a few of the events on Sam Rayburn (not in the Cowboy division). Lake Palestine 3/29 will be in the middle of the spawn on that lake. If you don't know where the spawning flats are on that lake, then you're in trouble if you don't go prefishing and find them. The guys that figure out how to catch pre and post spawn females will be the winners since all the bedding bass will have been hammered from people practicing. Oh and plan to launch early (5:00AM) as the marina ramps don't have a lot of room.
