Hidden Playgrounds - Keller Park Traditional Cache

There are so many little parks hidden around this city. Often they seem to never have any one playing at them.  My little one and I are going to do our best to find all of them and help everyone else find them as well.
We are going to try and keep these easy to find for the little ones but if there are only a few choices then you might need to look higher.  

Welcome To Keller Park.  It's a quiet little neighborhood park.  Almost everytime we have been around here we have seen a group of kids playing football on the next field over.
