In a timely post for families in the summer holidays, Simcha Fisher gives Ten Tips for Actually Having Fun at the Fair. Just understand that this may be part of the "two nations divided by a common language." In England, going to the Fair would be where you got locally produced honey, had a go on the coconut shy, and took children to the lucky dip before having tea and home made cakes. The Fair in this post sounds like what we would call a Theme Park (probably itself a borrowing from American.) I must confess that experience of taking groups of teenagers to these places makes me hate them intensely. The poor kids get ripped off soundly and get to go on about three rides unless they pay even more to jump the queue (cf. above photo from 2003.) I must join the Old Gits Society or something :-)
Still, I do understand that families have to suffer these places from time to time and I enjoyed reading Simcha's tips. I laughed at the advice:
Bring plastic bags. Trust me on this. Sooner or later, you will find yourself holding something that desperately needs to be wrapped up in a plastic bag.
