The short version: yesterday (Saturday), for the first time since Friday, 18 May, Michelle and I circled the block.
I've been told that it's a third of a mile around our block. The green part is about how far we've been going, although recent trips have found us a bit further around counter-clockwise, maybe to about the 11:30 position. Interpret as you will.
Anyway, we walked the dog around the block. It's been some months since the last time. A rough calculation, counting weeks and converting, is 168 days.
We would have walked it again today, but it was too in-temperate for us, what with the wind and blustery temps. Maybe we'll make the entire block tomorrow. Probably before dark, though.
