Yep... like Jerry said it's not that difficult to get a C & R record at most places if you're so inclined.
As for the kayak sharelunker, my fairly non-extensive research reveals that there have only been two submitted to the program since its inception.One at Purtis in 2012... And one at tiny Lake Ratcliff in 2006...
No idea about the Ratcliff fish, but I know the Purtis fish died pretty soon after it was taken to Athens a few miles down the road. I don't really blame the angler for wanting to submit the fish, but you can google newspaper articles where he recounts catching it down past the island and how it took him like 2 hours to get back to the ramp by paddling with it in his lap and stopping to dunk it ever so often. Not surprising that the fish was so stressed it didn't make it.
If I caught a teenager during sharelunker season, I think I'd definitely try to flag a bass boat in the area to see if they'd help me out by putting it in their well. If I was very close to a ramp I'd consider tying it on a stringer while someone came but only if water temps were such that the fish wouldn't be stressed. Most likely though neither of these scenarios would happen and I'd be too far to try and submit it to the program. I'd much rather have the pics and the memory than the guilt of stressing and possibly killing the fish.
