the problem here is that no one on this site will admit to leaving litter cause they know they will get stick, i even take an ashtray with me, well a tin with a lid but as jay said (x2gsd) one of the lakes that we are members of is disgusting and 2 or 3 others are pretty bad to the point that jay nearly never bothered joining. i must say though that the club did ban someone last year for litter abuse but it still dont put a stop to it. we have bailiffs that come round and give litter tickets and then come back later to see if you have left any, but it still dont stop them.
