You get to pick your own route, set your own pace, and have the opportunity to detour if you decide something looks interesting (or, as in the case on my last century, you get lost).

I do make sure that I have a cell phone and my wallet with me. I also let my wife know that I'm going to be on a "long ride" and about what time I expect to be back.

Plus, it's kind of cool to catch someone else out for a ride, while chatting with them, casually drop that you're on a century . They usually give you one of those You Must Be Nuts looks.
