cheers reg, was looking it up for my parents, paper said pewsey but yes your right just south of upavon.
I guess Pewsey is the nearest largish place, for reference in a national paper.
A pub I know a bit not too far away is the Crown at Everleigh, more or less nowhere on the very edge of Salisbury Plain...pretty old boozer, mentioned in Cobbett's Rural Rides.
I seem to remember the landlord had some problem with Van Morrison a few years back, or maybe it was the other way around.
But for weird, nothing beats the Bustard.
