It is a little slice of heaven in our urban hell, isn't it? The Dallas Arboretum with 66 acres of variously manicured green spaces and forest-y wilderness, plus 11 display gardens, which bloom and change with the seasons. The Arboretum is a "let the kids run wild" place, and stay-at-home moms use it liberally for those summer afternoons when the only alternative activity for a houseful of kids is homicide. For more things to do, adjacent White Rock Lake offers practically limitless venues, and under calmer adult supervision, kids can fish, feed the ducks, bike, bird-watch, paddle and sail. There are six great playgrounds and Dallas' first dog park. The Arboretum and White Rock Lake may actually be the best place to abandon your children for short stretches while you regain your parental sanity.
