If shelling out 26.7 million taxpayer dollars to buy the tiny spit of land on which the Miami Circle sits doesn't quite qualify as a boondoggle, maybe this does: The ancient site has been reburied. Discovered in 1998 and dubbed Miami's Stonehenge, the mysterious Indian artifact ignited the public imagination and attracted international attention. Six years after its purchase, however, an alphabet-soup of local, state, and federal agencies has accomplished virtually nothing. Experts warned that the exposed Circle was being threatened by erosion, so last fall it was quietly covered with gravel, sand, and promises that a few more years of paperwork would result in the park everyone was promised. Hey, the site lay there unnoticed for at least 1000 years, so what's the rush, right?
