Excellent point Amy (which is why I said I totally understand the change but don't understand a unanimous vote).

Your question inspired me to find a fascinating piece of data: 89 percent of school children walked or rode their bike school if they lived within a mile. Today, that number is only 35 percent. A much smaller number surely (but still significant).
