Pasadena is well-populated with somewhere around 150,000 souls. We have street lights, telephone wires, strip malls and all the cement you could ever want. We also have more access to nature than most city dwellers do. Not just parks (although there are many outstanding ones) but actual hiking in actual nature. That's one (just one) of the best things about the place.
Looking northwest from the northwest edge of town—so far northwest, in fact, that you have to cross through part of Altadena to get there—you can see across La Cañada-Flintridge to the mountains of the Angeles National Forest.
"Everything north of town (once you cross Altadena) is the mountains of the Angeles National Forest," you say. Yeah, yeah, I know. I just wanted a picture free of cement, street lights and telephone wires.
