I met Glyn Hunt a year or so ago (and he's the only person I know to have their own website - not sure what to make of that). It didn't take me long to realise he's as obsessed about benchmarks as I am trig pillars. I tried to ignore the pull. However I have just spent the week in Keswick with the family and realised quite soon on that the trig pillars were too high for us to reach . Sad but sensible when it's below freezing, ice/snow on top and the girls only had enough clothes to keep them warm at the foot of the hills, not 900m above MSL. So what to do except to cut my losses and start hunting for benchmarks? I didn't get too far as (a) the family only allow me out for brief periods and (b) we had no internet connection so I couldn't pre-arm myself with grid references to locate them.
So in the 30 mins I had last week (!) I/we found two.
Keswick Moot Hall and Keswick Post Office.
The beginning of the obsession starts.
