I am 72 years of age, in good health, but haven't ridden a motorcycle for many years. I actually took a class in riding a quad a few years ago and found it very fun and simple. I'd love to get involved in a group that travels to the desert to camp and ride quads on the dunes. I know the new quads are very expensive, so I'd appreciate advice on perhaps purchasing a used one in good condition. I do have a small pop-up tent which I've never used yet! I live in Imperial Beach, just south of San Diego, CA, and my name is Donna.
