I had a situation a couple days ago and I'm not sure what would have been the best call to make, so I just did what I could. I was driving into work, and the route I take involves a few turns. I was behind a car waiting to turn left from a dirt road to a fairly well traveled road, and watched as they acted like they were going to turn right, then went straight - they drove almost off the side of the road then went across. I thought maybe they were just lost, maybe didn't have enough coffee or something, until I got up to the intersection - and there was an entire box of screws scattered in the road - looked like 2" ones, hundreds of them - the lovely sharp ones that will puncture a tire. Most of them were concentrated in the closest lane of the main road (so the north bound lane, I was westbound, turning to get on southbound). Its on a hill, and it's not the most fun intersection to navigate, and not one you would want to say, pull over and put hazards on to get people to avoid it, because you'd just get rearended and cause a wreck. So, I did the first thing in my head - called 911, apologized that it was not an emergency, but it could potentially turn into one, and gave the description of what was there, and exact location. The call was maybe two minutes long. The 911 lady told me they would notify road commission to go there and clean it up. What would have been the best to call - this is in the middle of BFE, the closest "town" is about 5-10 miles away. Not much out there other than trees, the nearest house to the area is about a mile. I just didn't want someone to come flying over the hill and then blow out all four tires and wreck - but then, I needed to get to work. I don't like it when folks call 911 for stupid things, but I couldn't for my life figure out who to call for a non-emergency.
