I went Yesterday as I have done for the last Twenty or more Years,Didn't camp so I cant comment,did see a lot of drunks around the show ground,but that would be a mixture of Youth and a very hot Day
I was near enough fried walking around man was it hot,if I had a can of bow as was kindly offered to me by several I would have been pissed.
We host numerous events as well as a caravan site during royal welsh show week were we have near enough Ten Thousand people here,we split the families from the Youngsters eight Years ago,and enforce it,as it dosent half stop complaints the following morning
