The main intersection in Montpelier, Vermont, makes a chirping bird noise when the walk signals go on. This article makes me realize it must have been designed for blind people. I thought it was just some kind of typical Vermont eccentricity.
Nah, the Salt Lake Ciy signals chirp too. Hardly anyone jaywalks there too. I felt strange having people I didn't know admonish me for doing it constantly.
I have a couple of tickets (unpaid of course) for doing this as reminders to my days of fun visiting there.
