I think Mr Mounce has enough information to makeup his own mind. I checked on the map to see how far Glenrothes (Fife) was from Edinburgh.
Glenrothes does have a fine restaurant,the Tipsy Nipper and sadly Cumbernauld has only a cafe. Quite a good one, however. Both airfields will give you a friendly welcome. Kenny at Cumbernauld may be in a good mood if his team gets a result in Mancunia this week.
