I think it's very cool that it is still there.  I have driven by the one a few blocks from my house a few times, it's still there, but it looks like someone tried to take it down but I secured it too tight. And the one at the shop is still there for sure, untouched.  And one of my students drove by the one on Miracle Mile and she said it's still there.  I hope that its still there years from now!
