Your park may have some minor damages that can be repaired pretty easily. Maybe the water fountain is broken, the street lamps' lightbulbs have burned out or the swings on the playground need new seats.
Most of the supplies that you need for these types of repairs can be found inexpensively at your local hardware store. However, some repairs may require you to hire a professional. Take notes on what needs to be fixed, and determine if these are simple jobs that you can do with your family. We guarantee there are fix-it opportunities lurking all over your park -- you just have to look for them!
