Ah, the smell of a whole bunch of new vehicles!

The National Park Service is investing $5.4 million in the free propane-driven Island Explorer Bus service, according to Mainebiz.biz.

All 20 of the new buses will be in operation by this June.  The service will also be expanding it's fleet by 1.  Each bus costs approximately $240,000.  The current buses are all over a decade old.

The Island Explorer bus service, which is owned and operated by Downeast Transportation Services, carries riders between Schoodic Point, Acadia National Park and Mount Desert Island, and the Bangor/Brewer area.

Maine based L.L. Bean has also made significant donations to Island Explorer to keep it a free service.

The majority of the Island Explorer Bus service operates between June 23rd and Columbus Day.  For a full schedule and routes that the bus takes, go HERE!
