You're not going to believe it, but remember this? Well, I was driving down the same street, and out in front of the same house, in virtually the same spot was this.
I screeched on the brakes and hopped out for a closer look. Actual wood shelves, sweet little design on the brackets. No sign reading: "For the Salvation Army" or the like. Just as I'm picking it up, I see a person in the yard about 50 yards away. Should I say anything??? Turns out I should have kept my big gob shut.
"Hello!" I holler...."Is this looking for a good home?" The person (who reminded me of a hobbit) turns around, walks slowly towards me and says "That's my roommate's..I don't know why he put it out here. I better check with him first." I'm thinking: "Why do you think he put it out here? He obviously wants to get rid of it." I was too stunned to try to reason with her.
I asked her to call me if it's a throwaway and then I took the liberty of moving it closer to the house in order to A) keep it out of the rain and B) protect it from the grimy hands of someone like me.
