The Thetford Forest is one of the legendary woods of England. It's located in the East Anglia region, covering portions of Counties Norfolk and Suffolk. The forest covers about 200 square km (around 75 square mi.) and is the largest pine forest in the UK. The area was set aside for preservation after (the timber-devouring) World War I. The forest has held a number of legendary concerts, and it was used as a filming location for the wildly popular Dad's Army TV series in the late 1960's and 1970's.
