I made it there today, $5 for parking was a bummer. Alot of walking (which is hard for me). There was alot of plant material which was great. One vendor had fringe trees in bloom. City's green houses were open as was the mansion. They could have used more food and beverage vendors.
The new Vollmer Center is just great. This is now Baltimore's premiere location for gardening, birding, and outdoor hobbies.
