Hi mate,
on the 9th there is the first round of the NE Indoor Series, held at the YORCC club.
so, on the 8th track building (for the 9th) will take place after racing. To save time etc. we normally run an Oval track on the night before the indoor series event. It just means a big track doesn't need putting up and taking apart before track building.
hope that makes sense?
There was a thread about BRCA membership somewhere, i'll find it and post a link in a bit.
HTH,
Andy
