They screened a Luton away game at the Leisure Centre during the away fan ban i recall.
Which reminds me, Sangwell played Swansea in the play offs God knows how many years ago. They restricted the away allocation so the match was screened at the NIA the day after a run of ice shows finished so the rink stayed in place with the sparrow badge on the ice as a nod to the fans.
The only way to remove a temporary ice rink is to smash the ice up, shovel it into wheelbarrows and dump it outside to melt. I knew a couple of agency staff who really enjoyed doing that the next day....
