Untitled Sighting

My mother had called me out side in January because of large foot prints. The snow started melting at the time  .There were actual toe prints in the front - a big, a little smaller, etc.   It was shaped exactly like a normal foot but was 15 to 18 inches in lentgh. We had them the whole way around our property.  I walked in the woods days before and it went over my footprints and covered them.  Its stride was about 3 feet apart from left foot to right.
