From a Channel 10 Report:
"Local 10 uncovered more than 100 vehicles, paid for by Miami-Dade taxpayers that have been sitting idle in the Earlington Heights Metrorail garage for years. In total, an estimated $965,000 worth of taxpayer bought vehicles" have never been used.
Sure doesn't make sense that they are laying off people. I guess this counts as a boondoggle. Gimenez's answer for the idle cars: "Years ago the county significantly reduced the size of its fleet and decided to keep current vehicles on the road longer. By that time, the idle vehicles had already been bought and delivered. Gimenez said the idle vehicles will eventually be added to the county's fleet, as needed."
