I noticed you said "Greater Leeds" as someone who lives about 10 miles from Leeds, care to clarify that, as under the same name, Wakefield would be a nuclear dead zone as well.
Also, you missed off retired RAF Elvington, old WWII bomber base, still looked after as its a museum now, but it was officially closed in 1992, which with T2K, I doubt that the RAF would have closed her down with a major war on the horizon.

Also RAF Leeming is actually in Yorkshire itself, so it depends how you want to divvy up "Yorkshire" and "North East" on your maps.
