They're awfully hard to find, but there are some John Deere jerseys out there somewhere. (The ones I know the tale behind, they were team kit for a team sponsored by a lawn-and-garden place that sold JD, didn't come directly through the John Deere company.)

I noticed people seem to give me a wider berth on local streets when I was wearing a reflector vest, presumably because I looked more police-like.

Realistically, I think this is probably mainly your imagination, as most people are already going to swing wide or not before they have a chance to study your jersey pattern.
