Our house is 4.5 miles North, and Raymond, our caretaker, bikes to town. I see others going by occasionally. I know you can keep going on North past our house for a long while... at least to Mata Chica, which is as far as I have gone, and I'm sure much farther than that.
Anyone who lives there gonna chip in? Tony and Yvonne? Gaz? You all live North.
I think the main drawback to biking is the heat, if you are not used to it. Of course, I saw people jogging on the beach daily, while I lolly-gagged in the pool, and just *walking* very far on the beach during the day was an effort. Take water for sure.
