I was busy looking at the fish, so I didn't even see the cig until you pointed it out.
Ask your son what he thinks about noodling. It's a fishing term associated with fishing for catfish. Judging by where he lives, he may not be familiar with it. If he does know what it is, he's probably going to say...Where the hell did you hear about that? You can tell him the crazy lady on the internet told you to ask .
Don't spoil the fun and google before you ask . Let him tell you if he knows. If he doesn't, I'll explain. Of course, maybe you already know too, probably not though. It's nothing illegal or anything like that.
I'd say he's a smart man. I might stand on the bank where I could make a quick getaway and watch the action, but no way am I getting down in that water while someone sticks his/her hand into a hole in the murky water and pulls out heaven knows what.
