Canadian Flag

All three countries in North America have converged on tiny Yuma, Arizona. I was here this week reporting on the "virtual border" that companies like Boeing and ICX Technologies are helping to build.

But forget the immigration northward from Mexico. The place has been overrun by Canadian RV's! Each is staking out its patch of parched, barren dirt to while away the winter. The view consists of miles of rocky mounds and Tantooine-like sand dunes filled with scorpions and tarantulas. But the weather sure is nice.
