Report 63827: Multiple vocalizations and strange activity observed on rural north Florida property.

I would like to speak with a researcher or investigator preferably in the north Florida or south Georgia area about incidents that have been occurring on the property I live on for the last few years. I haven't seen anything but I've heard yells and growls that have made my neck hair stand up in the past. For 4 years I've worked nights but now I work days so I'm home every night so I'm noticing alot more now. Just about every night I've heard growls or stomping and have heard what sounds like imitated bird calls and also unusual smells. Just recently I found a tow strap with knots in it with a bundled up red ribbon material laying with the strap on a tree stump in my yard. The property is 68 acres of woods and pasture. There are neighbors but they are elderly and have no motive for playing tricks. Activity seems to only occur in the fall and winter.
