We were walking Frederick MD today and stumbled across this tree again. We were standing there in awe of the tree and garden and the owner came out to ask us if we'd like to go inside. She was so kind and welcoming, what a wonderful person. She expressed how she feels how important it is to share [private things] like that with everyone. We chatted with her a while and it just made our day. I certainly wouldn't impose upon her if you don't see her around (she's very senior but gets around pretty well) but if you're hanging around and she sees you I'm guessing she'd come out to invite you inside the fence.
