We moved a couple times when I was in elementary school, but we lived a block away for a while. In junior high I took the school bus. The bus stop was about 3/4 mile from home and my dad dropped me off by car. Then the ride was about an hour to school. In high school, we lived 10-15 minutes away by car.
Charlie will be walking to kindergarten -- it is 1/3 of a mile away. Most kids have to take public transportation to junior high or high school here (it's a matching system like medical school so you don't go to the closest school).
How far did you live from school growing up? How far will your LO live?
