As the crow flies (I've not seen a crow here, so, as the quails romp) not far, very short by air but a bunch of twirly streets in the mode I so dislike, differentiation of housing tracts, no bypass for a walker.
I live in an oddly to me charming housing tract of duplexes, so called townhouses, at the foot of the petroglyphs. I'm sardonic on all this as in that in my teens many years ago a friend told me she wanted to never live on Peach St. I didn't particularly agree then. Later I got it, when I spent years in beginning landscape architecture detailing housing tract landscape and then, designing a huge lot of it, for one of the top u.s. companies, not to brag. Not to brag as I needed to get away from that, big ugh, but the experience was useful.
Anyway, it is ironic to me that I live here, and like the area. Except for stuff I hate, like transportation.
Distance from Diane, I'd say twelve to sixteen blocks, a mile, by quail.
My memory of our visit, pre visit, was that at first you wanted to see only Bob and Diane, which I fully get. Diane was adament, No. Roger and I pushed at some length to get to meet you. I wouldn't push to get you to come see my house, which I would have liked. We ended up liking each other, eh? You and I are both tumblers, and were ok+ in person. I'm hard of hearing, as you know, but loved your voice and understood some of what we said.
I had a similar problem when I went to New York after 44 years, one of the crones being unyielding re my visiting her house, so I get the pressure.
