The Action Trackchair ($8,800) is the "Humvee of personal mobility solutions." Created by a Minnesota man whose son was paralyzed in a car accident, this heavy-duty transporter keeps the wheelchair-bound from being confined to sidewalks and streets. Its tank-style treads "open up fields and forests for off-roading." It's fit for trips to the beach, hikes in the woods, "even fording small streams" and "slogging through swamps." Hunters can add optional gun racks and mounts. "And, yes, that's right, it comes in camo." Source: Wired
