Forever Resorts bus drivers and a Mammoth Cave ranger prepare for the day. About 400,000 visitors tour Mammoth Cave every year; on a busy day, the propane buses, carrying visitors to remote cave entrances, can travel 400 miles in one day - all within the park. This year, Mammoth Cave received these four new propane buses via the DOE-Clean Cities/National Park Initiative. |
