SUGARLOAF KEY -- On a tiki hut stage in the middle of a saltwater pond, two crooners sing a boisterous duet to a crowd gathered at the Lazy Lakes RV Resort, a 28-acre rustic campground in the Florida Keys.

Not too long ago, the property had been slated for condo construction, but a Keys investor and a national plunge in housing values combined to halt the bulldozer. Now the land is part RV park, part outdoor music venue -- and a place for Nashville's Cowboy Troy and the Keys' Howard Livingston to let loose as the crowd sways and security personnel swig beer.

``RV parks were on an endangered species list, but the recession ended that,'' said Lazy Lakes' owner Joe Cleghorn, who in 2007 paid about $8 million to take over the mortgage from distressed luxury developers Cortex Acquisition Ltd.
