Take the East 215 Beltway and exit at Green Valley Parkway. Go north to Pebble and turn right (east). At the end of Pebble, turn right (east) on Wigwam. Mountain View Park will be on the right (south) after passing 3 side streets.
Since Prince filed for bankruptcy and no longer produces their superior, yet inexpensive Prince Championship Extra Duty tennis balls, I recommend the next best (low price) thing for longer lasting better bounce, the Penn Championship Extra Duty tennis balls. Most other budget balls just don't last as long or bounce as consistently. Although slightly more expensive, Dunlop GrandPrix Extra Duty balls are similar.
