UPDATE!
Once more, I drove to the Goodwill fig tree. It still beckons me! I parked in front of one of the three properties where I believe the tree lives. I look around and one house has one window open so I go there and knock on the door. The dog starts barking as before. His nose is right up at the door as he sniffs and barks at me. I would hate to see him face to face, that's for sure! I knock again, and again, and again, and again. The doorbell button is missing but I pressed the thing anyway. Nothing! No one comes to the door and yet I sense someone IS home. There is also a very nice corvette parked right in front of the property and in fact, the car is actually parked a few feet over the driveway entrance so it indicates to me that it is likely an owner or a resident who owns the car. Well, anyway, no answer again.
A walk around the house to the side without crossing the property line so as to not get in "trouble" with anyone. It's a quiet neighborhood. I took a quick picture of the shed where I see SOOOOOOO MANY figs that have fallen. Yup, it's the right house alright. Anyway, I go back toward my car but I'm trying to get the address to this house because I'm thinking that a written letter may be the only way to reach anyone. I see the address and go back to my car to write it down. Suddenly, a guy in army fatigues approaches my car and says "can I help you?" It was a bit intimidating but I quickly let him know that I was just want to ask a few questions about the fig tree in the back and possibly get some cuttings. His response was "what fig tree? It's a lemon tree!" I said "it's a fig tree" and I am interested in just getting a few cuttings. He said "I'm not the owner. I just rent from my friend but come back when you see a black car in front."
I think the guy came out because he saw me near his corvette. Otherwise he would have ignored me (as many times before). I don't blame him, I'm a stranger, right?
Okay, so no luck this time but I will keep trying. I'm getting warmer!
