Coupla old faves there. Will it be good or bad news if dewponds are 'only' leftovers from clay excavations? We used to get excited by them being lined with clay -- but then again it's all grist for our 'chalklands lack water but seem otherwise essential to Megalithic life' theory. The 'herepath', named that way because Anglo-Saxon armies came tramping down them (Heer is German for army). As opposed to Green Streets which, according to TME, are produced by animals tramping down the Ridgeways which in turn cause green lanes.
You wanna get out more, Borry, that's your trouble. (I'm setting you up for a trouble-and-strife joke.)
