We recently had the opportunity to go for an exciting ride at Mamre Homestead (St Marys) - for adults and kids alike. Even if you don't know how to ride a bicycle, no worries, as Segways are self balancing machines, and no prior skills are required.
You control the machine with your own body. Lean forward, and you move forward faster and faster. Lean backwards, and you are about to stop or reverse. It is fun even to ride off road, on a grass, or grassy fields. In fact, at Mamre's Homestead you'll find a 1.5 km Segway track to run on, reverse, and just have fun time out.
