It's rather interesting to be driving along and something goes screaming past the commercial traffic you've been watching, and there's no sound from
it.
I've been driving I 80 through Wyoming twice a week for the last 6 years. Fast moving green lights, horizon to horizon in lest than 5 seconds.
Orange blobs flitting around making rather tight turns. I see most of the interesting stuff between Laramie and Elk Mountain.
