I always looked forward to elections as a kid - A day of school
you can tell from the post

.
my eldest is in yr 6 ( 4th yr Juniors for the oldies like me) and hers is the only yr group in as the rest of the school is shut , they have been in the mobiles outside( nothing like the scabby things we had as kids, fully ITed up, Air con etc. lovely buildings ) . The reasons are varied for closure . in her schools case it is the fact that as well as being a polling station, the other polling station locally is also a school, and is shut as they have a central hall where the station is. the 2nd school also supplies eldests school with school meals so the school cannot open to full roll without hot meal provision . the 1 yr group can technically be "on trip " and have packed lunch.
aroundd here there isn't the other buildings available to use as Polling stations that have the capacity. the 2 polling station close to me always have queues and they have row upon row of booths. all the other buildings are just too small
