Seriously, did you even read the article? A direct quote -
Several parents presented credit cards to book rooms and passes on the spot, and the trip went on as planned. No conjecture on my part, I was quoting the article. We later learned that Trace Adkins' wife paid most of the bill which is awesome and kind of her to do.
(BTW, per Wikipedia -
Williamson County is ranked among the wealthiest counties in the country. In 2006 it was the 17th wealthiest county in the country according to the U.S. Census Bureau, but the Council for Community and Economic Research ranked Williamson County as America's wealthiest county (1st) when the local cost of living was factored into the equation with median household income.[12] In 2010, Williamson County is listed 17th on the Forbes list of the 25 wealthiest counties in America.)
That's not saying the kids didn't earn the money or that every child involved in the trip was rich, but once again, they were blessed to have some parents along who could indeed afford to salvage the trip for them which was my point from the beginning.
Tennessee has no state income tax so wealthy people are drawn to that area.
