Around here there is not just one but several fairs within easy driving distance each year. All of them are held at dedicated fairgrounds that are used for a variety of gatherings over the year. The one we went to last weekend is the traditional end of summer event for our family, and many others, as it is always held the weekend before school starts. It is, of course (this IS America after all!) bigger than the fair in my hometown. Perhaps not so much in the number of rides, but certainly with the sheer quantity of other activities! It's a sort of cross between a funfair, Women's Institute show, and Young Farmer's Club event.
I would have said that there was nothing like our local New England fairs in the UK but I bet if we visited the Cheshire County Show nowadays we would find it very similar to the show we went to last weekend. The Cheshire County Show was in somewhat of a decline when I was growing up and we never went to it but it has changed significantly in the past few years. It's just another reminder to me of how long I've been away from the UK and how careful I have to be when speaking about it. So much has changed over there in the last 24 years! The UK I left does not exist any more.
