Then I did the Roxwell ring, another 20 caches.
And I wound up on the west side of Chelmsford, doing Grey's walk, which isn't a ring, it's various caches dotted around. While I was doing that, I saw a trig point. Here it is, nestling in the hedge. The countryside around here is very flat, of course.
Here's the view from the trig point.
51 caches done today, and no DNFs!
