We are getting ready to open our pool. This is our first opening because the pool was just installed last July. Here is my problem. Our pool is in our back yard, which directly abuts a very large field. They currently are digging up this field to put in several ball fields. This construction is expected to last all summer. The cover on our pool is filthy dirty and I am nervous about what will happen when we take the cover off? How can I stay on top of the dirt?
