Is anyone doing any interesting armchair travelling this summer?

Do it all the time. To locate Village Halls, because they rarely have Post Codes and even if they do it could be the caretaker's house some distance.
And because I hunt OS Bench Marks (benchmarks.mister.red) I prefer to see the terrain first - narrow roads with no footpath forewarn me of the danger of any plan. And recently I found the Milestone Society website has 12000 logs and many photos, a percentage of which reveal Bench Marks - at lest 600 in total, and I don't even have to be there! Good as the Milestone Society is, they have anomalies and it is rewarding to go GE and see where the problem is or is in my imagination.

And http://what3words.com use GE - the URLs of which I publish on the Bench Mark website, so if people want to go find - I can point to within 3 metres. eg Sidmouth Anchor Gardens, where better to hold an outdoor ceilidh than at ///jumps.plus.scared or ///gladiators.bumps.games ?
or a singsong at ///sing.volunteered.values
