Where do you live where shade trees are not a thing? Genuinely curious. I've never known someone that didn't know what they were.
I live in Michigan and have four large trees surrounding the house, although we let their branches hang over the house, so 3 or so hours around noon, the house gets no shade.
There are essentially none where I live in SoCal (which actually bothers me a lot, because of how short-sighted it is but also because I grew up in the midwest and I genuinely miss having trees around). Most of the newer developments that I see and giant sections of LA and Orange county where I spend some time are little more than a sea of asphalt. There are trees in parks, of course, but they're more like decorations than something that serves a function.
