I found the original blue one of your home page in Laguna beach just a few days ago before return back to Florence! (Italy)
A really nice and curious idea and surprice!
Now it's in good hands...I'll take care of it! ;-)
Good luck for your project!
Not only am I thrilled that another pebble has been found and logged in, but DOUBLY so, because the finder is from my motherland, and it's the first pebble that has made it's way there. Such.Happiness.
Lorenzo, you really made my day, Paisano. :)
