Last summer, when I was commuting in the south Tacoma, WA area, I emailed the Franklin Pierce school district and the Clover Park school district (the two districts I rode through) with links to a few of my helmet cam videos.

Incidentally, only Clover Park responded. I suspect it's not a coincidence.
