Yes, you really do notice different things on foot than in a car. For instance: after the heavy rains this past winter, all the empty lots in the Irvine Spectrum area are full of weeds. But in spring, when the weeds are green and in bloom, those fields look an awful lot like meadows.
The lot (or meadow) in front of the Ford building, in particular, had so many birds wheeling and swooping above it that I stopped to watch, and also spotted butterflies and a ladybug that zoomed past my hand to land on the bag of allergy medication I always carry whenever I go somewhere to eat. (I moved it over to the hedge I was standing next to and waited for it to jump off.) A bit later in the walk I started to notice bird songs, and something I couldn’t quite identify as a very loud cricket, a frog, or just a gravelly-voiced bird.
Not all the empty lots look like this. The one nearest the building where I work is, at this very moment, being reduced to stubble by some guy on a power mower.
I’m surprised even the weeds are still green since the last time it rained. I mean yeah, they’re weeds, and hardy — but yow.
