Lol, cows... I hit a cow in a cage about a year and a half ago. The young ones can be similar to deer. $1500 worth of damage
Around my parts, most of the curves are unsigned and worse yet, some of the signs are just plain wrong. Most are too slow as you would expect, but there are a few that are too fast. Those can catch even the most experience riders off guard if they don't know the route.
