Urbana-Champaign Bicycle Commute

OKay, called non-emergency number for county sheriff, who took my name and address ("where are you now?") and ascertained that it happened yesterday and wanted an exact address ("I wasn't inclined to go back and look, it's the only house there"). I told him I"d called animal control but they hadn't gotten back to me, but that I was concerned becazuse it was a very aggressive dog. The phone rang in the background and he said he would see what he could do for me, okay?
... and two minutes later I got a call from somebody who does stuff (who'd read the report) and took more details and said all the right things (as in, "we will do a quarantine and check hte vaccination records and let you know.") And to call her (giving her name) if I hadn't been called by the next time she was on duty (giving that time). So thanks, Person Who Does Stuff. Hope it works out.
