A short walk along one of the Greenway trails you will be searching for larger container with a bison tube in it. In the Winter it will be the same larger container, but without the fun parts.
Back in 1958 a meteor struck near Downingtown, Penn. Out of the meteor came a jelly-like substance. The "Blob" would consume every person that it came into contact with. It was finally stopped when they discovered it didn't like freezing temperatures (just like this one). I was walking along the trails when I thought I seen something odd. I had heard of a toxic dump nearby. I reported it to the authorities and they told me they contained it and cleaned up the site. The coords are for the spot that I had seen the odd substance. This cache is more fun to find in the warmer months as the "fun" part of it is not Winter friendly. There is a FTF prize of an unactivated TB if you are brave enough.
