Well, I was able to wander into a patch of old trees on my route
today. From what I've been able to gather, it was spared from being bulldozed because someone noticed that it was the site of a slave cemetery. The right folk fought the developers, had the land declared some kind of historic site, and thus the trees have been spared.
I had noticed for a long time that there are some big trees in there. Not least because one of the trees visible from the street is a bottle- shaped poplar large at the base which quickly tapers. Looking at the grove, I could tell that there were some even larger trees partially hidden.
Things like this are always amazing to me. To think that these huge old trees exist in the midst of a vast, urban sprawl is both amazing and pathetic.
