brush with the law?

Zeke and mom tried to go for a run at the Summerville Sawgrass trail but they still have our area off of Luden Drive blocked by all kinds of heavy equipment. So we had to come up with plan B and decided to try to swim at the Ponds. Though it was cold, Zeke swam some and then Z and mom played frisbee. Zeke made some killer catches. Just as we had loaded up to leave, two sheriff's patrol cars pull up behind us; one gets out wants to know what we are doing and if we live there. We said no and just playing frisbee. Then he told us to have a good day and left. Kinda random, I think where we were is open to the public, maybe we just looks shifty.
