Commuting from Annpolis to DC Area
It really depends on what time of the day you are going to try to make the commute, but 45-50 minutes is my typical commute from Shady Side (just south of Annapolis) to Greenbelt. However, it can be 60-75 minutes at rush hour.
Learn the backways to avoid the beltway back ups. Good luck, I love the Annapolis area. It is a sailors paradise.
