Being aware, and decent reflexes, has saved my butt many a time, just like the walnuts! I live in rural east TN. Black top county roads. Their is a mix of everything on the roads. Trash, grass,leaves, nuts,dead animinals, live animinals, wet spots, oil spots,drunk drivers, texting drivers, and more. The ONLY place I feel safe opening it up, is on a couple half mile straights, with great viability. Most of my riding is done at the speed limit (45) +or- 5mph. Never drive faster than you can see! Blind curves mean slow down!
Like mentioned easier, Ride the loop looking for trouble, then on way back, open it up a little!
