I wonder if any of it can still be found in the river that runs through our city. (you know, the one they attempt to dye green -excuse me- lighter green, every year)
I really doubt there's any in that ditch. I've been by there and frankly I'd be surprised.
Now that I think about it though there might be some that hasn't yet evaporated from that little incident with the Dave Matthews Band's tour bus and that sight seeing cruise ;-)
