Students attending a summer school program in Louisville, Kentucky, were treated to lessons on American liberty that focused on the superiority of the free market, the gold standard, the American Constitution, and the failures of tyrannical regimes. USA Today reports: During the five-day Vacation Liberty School, talks, skits and activities mixed conservative values and early American history, including stories about how colonists' prayers once helped turn back a threatening French fleet and the principle of equal opportunity, but not necessarily equal results.
