"Take a look at the hill on the east side of the dam. Nice little bunker up there. Great little pearch for a sniper."
You probably know this, but there are two of those. They are machine gun positions that were manned during WWII.
I have driven from here to Gunsite three times since 9/11. Twice with 3-4 AR15s in my vehicle, all openly wearing a handgun. However I didn't go across Hoover Dam. I haven't gone that way for years. It is nothing but a PITA. The dam itself is a traffic jam even without security. The winding roads cut through the mountains mean a seriously decreased speed. The area is heavily patrolled, there are people walking across the road........ That is the good part. The bad part is that when I used to go that way, the road was two lanes for miles on each side of the dam. It is a given that two or three retirees with their travel trailers or motorhomes will drive at 35 miles an hour extending your trip by an hour. I detour around the dam by going from Kingman to Golden Valley, to Bullhead City, to Laughlin, to Searchlight. If I have no evil assult weapons in the car, I cut through a tiny piece of occupied California to get to I-15. I cut across from Searchlight through Nipton California bypassing Henderson and all that.
