It's like magic, in fact, it may just be magic.
I've done this several times, and until yesterday I always had placed a hand painted sign proclaiming "FREE" beside the item. Yesterday, I just placed the metal bakers rack leaning up against the trash bin without a sign, then I drove up town to the Red Box for a movie, and when I returned, it was gone.
Magic. This is so cool. The ultimate in recycling, re-purposing, and reusing items. Obviously it looked useful to someone, and it was in good shape, so off it went to parts unknown. I have done this a few times with various items, and all have vaporized within a very short time. Being free kinda hastens the magic along, I think. I have stopped at yard sales and spent $5 on a little wooden bookcase that I repainted and now holds books, DVD's and CD's. If I have a need, and I see something I can re-purpose I'll spend the $5, and re-purpose an item, but when something is free it tugs at the Yankee in each of us, and actually makes us stop the car, and claim the item in the name of frugality.
A frugal person visited me yesterday. Thank you.
