Do the road with magnetic paint and add magnets to the cars. Playroom or little boy's room. I think the better idea would be to place this on the floor rather than teaching kids to drive cars on the walls.
St Regis Hotel New York-lovely. I like the woodwork, floors, and the grayish paint color of wall with the black door and black and white floor. I wish I knew all of the paint colors but especially the wall color.
