SHEFFIELD, Mass. — A memorial in a remote corner of Massachusetts that marks a 1969 UFO sighting has been ordered moved, but one man who experienced a close encounter is objecting.The 5,000-pound memorial in Sheffield was installed in 2015, but was moved about 30 feet a few weeks later when it was discovered it was on town land.Now, Sheffield Town Administrator Rhonda LaBombard tells The Berkshire Eagle it has to be moved again because it's on a town right-of-way easement.
