Long line of cars and motorcycles queued up at the entrance. Every parking space in every trailhead overflowed. Site seeing helicopters flying overhead every twenty minutes. The local grocery store crazy busy all weekend. Would I like to have Red Rock to myself? Sure. But it is no big deal. Nobody is out protesting. In fact, nobody complains about it.
I have lived in San Francisco. Same deal. I don't remember seeing people with signs saying "go home"
