If we decide on Popham, as that's just a short hop from White Waltham, I wouldn't mind detouring to pick someone up on the way, or I could take someone from WW and we could go the scenic route eg via the White Horse or whatever. One spare seat in Cap 10 available. Ability to map read whilst inverted an advantage but not esssential.
Other poss venues: Old Sarum? Compton Abbas? Don't mind really.
