the one year we were walking my kids to school, we had 8" of snow in 2 hours, started right as the last buses were dropping the kids off at school. Then the school district, at 8:30am decided to call school off. So all the parents who had almost gotten to work, and all the people on their way to work, and all the buses got caught in a traffic jam with all the loonies who have to run out and buy up all the bread and milk at the hint of snow got got in a snarl that literally stopped the city in its tracks for the entire day. There were kids who didn't make it home from school until 8:30 at night. People were making snow men on the sidewalks. My BFF was on her way to pick up her daughter and was literally getting no where so she just left her car to go up to a house and ask to use the restroom!
My Florida kids lucked out, I walked to get them and we walked home through the college campus. Some college kids were out and had our kids help them build a giant fort and pulled my kids along on garbage can lids. Great memories for us, nightmare for most though.
