The city set aside some park land at the northeast corner of the lake. Muenster Milling Co. (pet food) kicked in $25,000 to start a private fund-raising effort. And Texas Rangers broadcaster Eric Nadel did the cheerleading. But the basic act here is the dogs. They run, they play, they slurp, they jump. Amazing! This new dog park, the city's first, is the place to go to see how dogs would behave if all the human beings suddenly left the planet.
