We live next door to a small city park where a school bus picks up neighborhood kids.  About the last month of the school year this bicycle started showing up in the park.  Sometimes it would be leaned against a tree like this; sometimes it would be leaned against playground equipment; once it was left in our front yard; sometimes we would see a boy riding it home.  Was it a shared bike?  Was it a stolen bike?  ( I thought of The Bicycle Thief)  I guess our neighborhood is safe enough that it could be left at the park in the morning to be picked up after school.   It had a chain with lock combination but it was never locked and was in good condition.

School was out last week and we have not seen the bike again.  Maybe it will appear again in the fall.
