Lessons Learned (so far)

• Balance is key.
• The availability of a stationary hand rail is an
  important piece of the design.
• The stair will need to rise smoothly and evenly
  (some type of guides?).
• Going up and down are different problems.
• Bus drivers wont admit to wanting something
  faster (I would never rush a passenger.)
• Contrary to initial belief, having one foot/cane
  on the upper step while the lower step rises
  feels more stable
