I ride out in the country alone, too. It's generally not quite that remote, but it's not exactly populated either. I try to minimize the risk by carrying a cell phone, having the gear needed to fix a flat and telling someone where I'm going. I suppose I could carry pepper spray or the like, too.
Wherever your ride and with whom, there's risk involved. We can minimize and prepare for those risks, but we can't really eliminate them. I think I stand a greater chance of getting hit by a car than getting attacked on some country road so it doesn't bother me too much. I'm actually more afraid of stray dogs than anything! I've perfected the art of yelling "Back" at the top of my lungs.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
