An account in Hillsborough County, Florida

I went down to Florida with my family while my dad was working there. We didn't want to stay in a hotel because we had just bought a camper so we decided to go camping. So we stayed at the Hillsborough River State Park. One day I took my bike out around 2 in the afternoon. The camp had a few trails to ride on so I decided to take one. As I was riding my bike, I stopped and looked over the ledge at a few alligators I spotted. I heard a rustle in the trees and thought maybe it was a gator so i got steady on my bike and got ready to take off. As I was looking around I noticed a tall dark brown hairy figure just standing there looking at me. I thought my eyes were playing tricks on me so I looked harder at it and It took off running. I would also like to note that it was running on two feet, not four. I rode my bike back to my camper as fast as I could and elaborately told my mother and my sister that I just saw Bigfoot. They both claimed I was crazy and told me it was a black bear because the camp guide told us not to leave food out because they had some of them in the area. But I am most certain that this was not a bear. this "Thing" stood at least 7 1/2 feet tall and ran upwards on two feet. I know what I saw,and ever since then I've been fascinated with this creature. I know its out there!
