I ride mostly on a highway, but there isn't a huge amount of traffic. Cell phones are a no-go in my area (the boonies), I just let my hubby know where I am heading out and if I'm not back in x-amount of hours, come looking! I am more concerned about wildlife (bears) than kooky humans, though you really never know about humans either sometimes... it's good to keep your eyes open!

I never really worry, but I also have family/friends telling me I'm crazy for riding alone. Hey, I'd rather be out on the road than in a gym!
