The catchment area for Abingdon would be Oxfordshire, but I'm still none the wiser at your remarks! However, Beagle is probably right.
I believe Kinross was chosen as the nearest location to Leuchars, which, if you've been to the airshow, attracts a huge audience of 30k -45k each year. That's mainly due to the fact that its the only large show north of the border, but as its not on this year, Kinross may well be better attended than Abingdon.
