The Scoop on Baltimore, MD

We have visited Baltimore, MD several times. Never before did I know about free transportation! If you park at Fort McHenry, you park for free. Even RVs. Just outside the gates, you can catch a free bus that travels around town. We didn't learn this, of course, until AFTER we visited there several times but I wanted to share the knowledge.
We went up in the "Top of the World" World Trade Center. Awesome views. We visited the Edgar Allen Poe House (there is free parking there, too, but you must walk a ways to the bus stop) and the Poe Family Grave site. Contrary to the Poe House (only open certain days of the week for limited hours, call ahead) director's advice, you CAN walk to the grave from the house and you can ctch the bus near the grave. We have visited the Inner Harbor where we splashed in the fountains on a hot day, toured the ship, aquarium, and several museums. We toured Federal Hill and Fort McHenry and, of course, completed the junior ranger book.
Six Flags isn't too far so we splashed at the water park then went on some rollercoasters in the evening. Washington, DC isn't all that far either.
We usually stay overnight at the Walmart near Greenbelt Park, since quiet hours at the park prohibit the use of my noisy generator but there is a huge park, skatepark and shopping area close to Greenbelt and we do go in Greenbelt for $16 to shower, dump, and fill with water, as needed. There are no hook-ups there.
