I went down the M40 today to do the Despicable series, which is very new. 50-odd caches in a circuit. I found a place to start, such that I could bomb out halfway round, get back to the car for lunch, coffee, a bit of a rest and a battery change. So I did 32 caches before lunch, and 28 more after.
There were some very horrible tracks; chewed up very badly by horses (perhaps that should be hoofed up) and rather muddy, so I was wheeling the bike more than I'd hoped. At one point, I emerged into a field, where there were three hares cavorting. And I saw lots of lambs frisking around. The whole outing took 8 hours.
