Report 10740: Couple finds tracks in backyard pond

I live in henderson county in west tennessee on the border of the natchez trace state park my home is about a 1/4 of a mile back from the road and is surounded by forest i have a small man made pond near my home that dosent have very much water in it right now my husband was doing some yard work around it when he noticed large foot prints down in the mud and some that were in the shallow water he called me outside to take a look. to me it looked like there were three sizes a very large pair and then two smaller pairs although the smaller pairs were still much larger than my husbands foot even with his shoe on you could see 5 toes and the arches in the foot i doubt that they could be anything else but this worrys me because i have an 11 month old baby in the house and my husband leaves for work at 3:30 a.m. every day i have a dog but she is very small
