Even exploring the US has its potential dangers. I'm parked at the Imperial Dam LTVA near Yuma now, and looked at a map yesterday to find nearby National Parks or Monuments. I discovered the Organ Pipe Cactus National Monument was about 3 hours away, so I went to the National Parks website to learn what I could. Here's a quote out of the "Safety" page for the park:
Organ Pipe Cactus National Monument is a safe place to visit. However, illegal border crossings and activities, including drug smuggling, occur daily. It is unlikely that you will encounter any illegal border activity but you should be aware that such a situation is possible.
It would be an interesting place to visit, having many varieties of cactii and wildlife. (Including Gila Monsters, which would be quite a sight.)
The park abuts the Mexico/US border for several miles, which led me to read the page about park safety. If I decide to camp there, I will have protection next to my bed. And I don't mean a big dog! Or a shotgun, as was recommended recently.
