Transatlantic flights to Scotland land at Glasgow or Edinburgh Airports, both of which are in the central belt and make good centres for touring and are handy for visiting Stirling. I'm planning to be in Edinburgh from 3rd to 8th February and in Glasgow from 22nd to 25th February, so could maybe meet up. Or if you decide to stay with P1M at Ferintosh I should be able to pop across to Dumfries for a meet.
