I saw a fire on the side of the highway. In fact, it was pretty close to my car. I called 911, and got a busy signal. Fortunately, I was in my home city and was able to contact the local police department's emergency dispatch center via a 10-digit number they published on their Website. I do live in a highly-populated, multi-county area where all highway calls go to a central station, so I can't exactly blame the dispatch center staff. Edit: Although, I would have appreciated a note that could tell me if someone had already called in the incident.
