Do you see the long narrow park north in the middle? That wasn't there when I was living there. That was a CANAL. The hydraulic canal, to be precise. It was part of a system that brought hydroelectric power down from the West Canada Creek, and even when I was a kid it was substantial. Overgrown, yes, but all fenced in, and, well, the depth of a canal. The street was a bridge when I was a kid. Dad and I went through the chain link and he showed me the canal, and the old egg crate factory it used to power, and there were frogs! Hey - frogs are cool when you're seven.
I can't say that I'm upset, per se, but it's really disconcerting when major geographic features... vanish.
