the fact that there's no water up there is the whole point - in the days before bridges were common, you really didn't want to be crossing rivers very often, especially if you were droving a load of moody cattle

something we take for granted now

the the whole Aylesbury-Avebury run is 84 miles - that's 12 miles a day over a 7 days, which could be a sod if you're carrying all your own gear. If you get the "Ridgeway Companion" (4 quid on Amazon), it lists all the b&bs, many of which will take your stuff to your next drop

otherwise, you could get the train to Goring/Streatley, and walk the 42 miles to Avebury - that's what we were going to do this week (sniff, sniff)
