On the same trip we were going to go and see Hoover Dam but on the way in we saw the checkpoint with all the "officers" rummaging through folks' cars and deciding we weren't going through that, made a hasty u-turn. I am half surprised somebody didn't come after us.
Ugh! Oh no about Hoover Dam, that’s so sad you didn’t get to go! IMO that it’s all a sham to hassle US citizens.
I don’t leave the house much (work at home) and don’t drink a drop ever. But, if I saw these DUI checkpoints, I would turn around. We have the home team advantage in the desert, people can see the checkpoints from a long way off, even in the city.
