A growing number of residents in California are clamoring for outdoor fire pits and fireplaces as the "fire element" gives them more reason to go out and enjoy the evening in their backyards. "Almost everybody asks for it. Fire adds another element to the yard. It adds ambiance and the drama of the flames. It gives you another reason to go outside," said landscape designer Michael Glassman. Home Depot's Stacey Spillman said propane-fueled fire pits are among the major trends in this growing market.
