I wish I had the budget to allow me to do that.
While I making your card I wondered if you'd recognize the source of the photos -- it's on 12 Mile, over by D&D Bicycles, if you know where that is. The garden's by Historical Courtyards and Gardens
. According to the web their office is over there somewhere, but all I noticed was the garden itself and the spot behind the row of buildings where they park their vehicles.
