I think it is more down to the anglers than the alcohol itself. When I do a couple of nights with my mate, wherever it is, we always take a few beers, especially now the warmer weather is with us. There's nothing better than sitting outside the bivvy and having a couple of beers as the sun sets (hope that doesn't sound too camp!). We never start shouting etc. and make sure that the tinnies go straight into the bin liner, not leaving them strwen around the bank until morning. Unfortunately I have witnessed the other side of it, where some people find it necessary to make as much noise as possible with portable CD players etc. blaring out and generally making themselves look like a bunch of t**ts who've just had their first pint. I think it would be a shame for the majority of decent-minded anglers who like a couple of beers on the bankside if this was banned because of a minority of inconsiderate anglers but I wouldn't criticise the fisheries because at the end of the day, fish, fishery and fisherman safety is paramount.
