rv1, You have to give folks a little more info: I know Miller Park is the Brewers' home field in Milwaukee, but many people do not. If you are looking for a park near Milwaukee with recreational facilities (pool, etc.) , I think you are out of luck. For convenience to Miller, your best bet is the Wisconsin State Fairgrounds RV Park in West Allis. It is just a parking lot with hookups but is just few miles from Miller Park and a few more miles to downtown and the lakefront.
