Other than Bigfoot and Mt. Lions in PA I mean.........

I'm talking like objects or little oddities.
I remember myjunior year in high school I was hunting a woodlot not far from my home in south eastern PA after school and saw something shiny at the base of tree off in the distance. (No it wasn't a UFO

)
It looked so out of place where it was that I had to check it out.
When I got there I could see it was a deflated shiny mylar balloon tangled in some brush and it had a string with a laminated card attached to it.
Turns out it was from a little 8 yr old kid in a town in Western Iowa who was part of a baloon launch with his class.
The card read:
"My name is Little Johnny (don't remember his name), and if you find this balloon would you please send this card back to me at......:"
I thought that was pretty cool so I took the card home and wrote him a little letter (pre-email so yeah a real letter with a stamp and all![:-]) showing on a map exactly where I found his balloon.
A few weeks later I got a letter from the little guy thanking me that he had won his contest because his was the only balloon returned complete with little hand drawings of Bart Simpson on the white lined notebook paper.
