I rarely fish anywhere which doesn't allow C&R after limit, for exactly that reason. I remember fishing Lechlade once as a guest on a corporate day thing (not a freebie unfortunately, just a couple of quid off full price). Two and a half hour drive and had 4 big lumps of lard within a couple of hours, and that was that for the day (since I wasn't going to pay another £50!). I messed about on the brook around on the lake, even though I only had a 10' 7wt outfit with me

and I managed to tempt a small brownie, then I just spent the rest of the day chatting to others, drinking tea and waiting til my mate had his limit so we could drive back. Not my type of venue, not my idea of a day's fishing

The fish didn't even make particularly good eating.
