you'll need your own tables/chairs but mains power is available
it's just run to relaxed regional rules i think as almost nobody has 2009 legal cells and its not a brca sactionaed event so shooudn't be of concern
, don't worry about your tp cells from last year Dave they should be fine to use as long as your car is above the minimum brca legal weight
many people were using them at the regional at batley on sunday, so long as you take care when charging etc
