I don't really remember them in '04, but remember them in '87 and '70.
In '87 I got a new company truck at work. I had found one of the shells/cases and put a dab of silicone caulking on its feet. Stuck it on the hood of the truck like a hood ornament. It was there probably 3 months till the owner saw it and flipped out.
In '70 I can remember a buddy and I riding our bicycles, looking for pop bottles along the road. Remember the 2 cent deposit? Anyhow, we came along an isolated area of road where there was a tree just loaded with cicadas. It creeped us out and we soon got outta there.
