Have not seen one yet but there are rumors of a giant 8-foot tall hairy creature called Bigfoot roaming around. I hike a lot in the woods here on East Coast and have not seen one yet. Rumor has it there are many more sightings in the Western part of the USA rather than the East Coast.
There was a newspaper article about a strange fish with teeth that can walk on land appearing up in the Maryland area and a few of these creatures have been caught. The local authorities are very concerned that this non-native fish is a threat to the local fish population.
