3days ago I was shooting photos in Thetford forest. I had parked up and started walking along one of the tracks. I noticed a side track, turned my head to the right to look down it, and there was a HUGE great animal trotting toward me, which if it was a fox was very unusual.It was a deep chocolate brown colour with BLACK edges not a single trace of white on it. AND it was big, as big as a sturdy Alsatian dog. Has any one else seen anything like it?
