a few 'odd' track dimension questions

[Chris Doughty]

how big are tracks like southport, bury metro, CML Raceway and Kidderminster? (floorspace width and length)

how high is the 'top' of the rostrums at those venues?

how much 'inside' space would be needed for a full national pitting (just inside pitting space, no tents or cars)?

if I think of some more I will add to the list...

any help would be appriciated
