Today my son's school and school district had a "International Walk to School Day". The students could walk, bike, take the bus or carpool to school. My son chose to ride his bike to school. There were a lot of students who rode their bikes to school today. The bike lock up area was full of bikes. The bike lock up area is very small so there wasn't a lot of room for bikes. Only a few students ride their bikes to school on a regular basis. So I walked to school to pick him up after school. My son was tired after he biked home this afternoon especially since it was a warm day.
