Actually, I believe it was the the government. Too many people are on to area-51 so they hope all those area-51 researching people are lured to the KFC logo....in the months to come around the area shall be McDonalds, Jack in the Box and Sonic Logos, In and Out should be around next year as well.
The government wants anyone looking at/around Area-51 through google will just get hungry and go stimulate the economy...
Oh yeah, they're using the mole people to do the labor. Because only 6 humans understand moleish the conspiracy has less chance of the truth breaking...
