Once a veteran marathoner, 74 year old Bruce Maynard now battles major knee problems — but his age and physical setbacks are not thwarting him from planning his upcoming journey across America in a solar powered jogging stroller named ‘Sam.’ Outfitted with a foldable solar panel (which powers the device in tandem with a battery), ‘Sam’ is Maynard’s mobile office — complete with a computer stand and work table — as well as his campsite via boat-hook poles that will be used to construct a trusty tent. Maynard will be ready to roll on his six month trek in April, after undergoing trick knee surgery. Visit Inhabitots to read more about his inspirational plans for this journey.
