I love the O Street Mansion. I had a big birthday celebration for my most recent special birthday and have enjoyed several other activities there. Yesterday was no exception. The book talk was inspiring, the authors engaging, H.H. Leonards friendly and welcoming. All the staff was friendly and helpful. I had not known about Rosa Parks' connection to O St. and was moved by visiting her room and the video that was playing in it. Thank you for all your cultural and socially-relevant gifts!
