The Garrett County Historical Society had one great museum in Oakland MD another in Grantsville. You can check out my tour of the Oakland facility by clicking HERE. Now there are three with the opening of the Garrett County Transportation Museum. Two floors of various modes of movement on land and water for every season. There is also a great collection of transportation related artifacts from Deep Creek Lake and Garrett Counties past.
Below is a video of a trip I took. It is in no way a substitute for an actual visit. The two museums make a great trip when your looking for something else to do in the Deep Creek Lake area. The best part is admission is free.
