Head east on Spring Valley Road between Preston and Hillcrest, but not too fast. Drive quickly and you'll miss one of the most amazing outdoor art displays in Dallas. There on the right, turn into Valley House Gallery & Sculpture Garden, park your car and walk along a pebble path that allows you to look and linger on the lush grounds of the home of Kevin and Cheryl Vogel. Currently situated among the reeds, vines, flowers, trees and ponds on their 4.5-acre wooded estate are abstract metal sculptures as well as sculptures of people in various states of repose and play, works by Charles Umlauf, Mike Cunningham, Charles Williams, Nat Newlean, David Hayes and Frederich Sotebier. And there is no such thing as a trespasser at the Vogels' garden—not Monday through Saturday between 10 a.m. and 5 p.m., and not if you stay away from the Vogels' private residence, which is also on the grounds. These works of art set among the garden are available for public viewing, free of charge. Of course, if you want to take home any of these sculptures, or any works of art inside the gallery, which is also nestled onto the grounds, that will cost you.
