These are Berkeley lawn mowers. Sighted from the Berkeley off-ramp, it gave me quite a start. I couldn't smell them from the car but I'm not sure their perfume is much better than the smell of a gas mower. It's a really steep hill which would be hard to mow. I tried to park but there wasn't any place to pull over so I just stopped in the middle of the frontage road. I mean, wouldn't you?
