Without a boat you can see the launch, if you want to get up that early, and the weigh-in. Some pros will stick around for autographs and to talk, others will bolt right out of there, especially if they've had a bad day. There are sponsor booths where you can check out and sometimes buy products. If you go on Saturday, some of the pros who didn't make the cut might be in the booths so you can chat with them. If your son wants to meet a particular pro, ask one of the B.A.S.S. folks, they might be able to help make it happen. Good luck, have fun, and props to you for encouraging your son in fishing!
