This is the Morongo Casino just off Interstate 10 on the way to Palm Springs. I pass it regularly when I go out to the desert for some stargazing. I took this photo around 3 am, and I was lucky to get it because a security guard shooed me off right after I snapped the shutter. I asked him (nicely!) why the casino cared if I took a picture, and he just shrugged his shoulders. He had no idea. Just following the rules.

Living in Palm Springs, we pass Casino Morongo whenever we travel to LA or any other point west We affectionately call it the Tower of Terror.
the pediment looks like something from 'forbidden planet'
i can imagine 2 reasons the casino might care. 1) what happens in vegas mentality, where they don't want and of their guest/customers being spotted doing something untoward. 2) there's tons of cash floating around at a casino and they don't want criminals casing the place for some sort of robbery.
Next time I go that direction I will definitely go to their parking lot and take as many photos as I can manage.
Is it because the parking lot is empty?
No pictures because that is a damned garish, ugly place.
If you’re standing on a public right of way, you can tell the casino to piss off. I’m guessing the casino owns all the roads around it though.
Or at least the Morongo Band of Mission Indians owns the roads.
They ever hear of Google Maps Street View?
