30 miles out-one-way can be just enough to get you far enough away from home to take a hotel room for a night and call it a "tour!" Then you can either ride home or take public transportation home the next day.

Doing an overnighter with just your bicycle can be a really memorable experience. I do it at least twice every summer. I miss having my wife with me at the end of the day, but I love the feeling of "roughing it" and living with the bare essentials for 24 hours. Try it sometime, and let us know how it felt!
