I guess these are all over my hometown; this is the second one of these I've seen this week - it was on a secluded spot on the common, found when I went off the main path because I was self conscious while walking behind a couple up ahead of me on my lunchtime walk.
I've now walked 21 out of 100k on my Strava challenge, and am going to Dad's place tonight in our new support bubble. Hopefully we'll get to have a walk together tomorrow; I'll definitely suggest it.
