I drove a stretch of road out near Stateline last night that was probably about a mile long. I drove it again first thing this morning and saw some pretty gruesome sights that hadn't been there the night before. The roadkill toll in that one mile alone included a turkey, two deer, a raccoon and one REALLY big bull elk that must have left some serious damage to someone's car. I wanted to take a picture of the elk just for the impact but thought that might be too ghoulish.
My point is that its getting dark earlier and its that time of year when the animals come back down to feed, so maybe you want to slow it down in rural areas, especially after dark, and be observant out there.
