Sylvia is correct-the Jack Carter Park is a great park. it's leash free-so you need to keep your eye on your pet because you never know how dogs will react to each other. Frisco has a "Doggie Play Group" where the owners and their pets get together and do activities together. Several cities have meet-ups as well-where people can find a group with similar interests and they meet-up.
I would ask what other criteria is important to you in a home and go from there. Are schools important, distance to work, etc...This is actually a great time to think about buying in this market. Lots of inventory on hand.
If I can help you any further please let me know. My office is in Plano.
Best of luck to you,
