This alien dude is new. It's a store near the start of the highway that calls itself "The Alien Research Center, Area 51." There appears to be no research going on there. The facility also claims to be a "museum" but there were no displays apart from the original E.T. Highway sign. It's just a gift shop, open only Fri-Sat-Sun. The sales clerk said it had been open for about 9 months and was owned by a George Harris in Las Vegas.
I was there for a while before I realized, "Hey, this is a total rip-off of my Area 51 Research Center!" I'm not particularly upset, though. I don't expect this place to last for long.
