Check out the trails at the Heard Museum and Wildlife Sanctuary in McKinney. I am also working on bringing a boot camp there. More info at http://www.myhealthforlife.info.

I second the Heard - good prices and great for kids too. I believe you can go on the Collin County website and get info as to the trails.

There are also tennis courts (I think 10) at Plano Senior High
