I once drove the highway through the white sands missile range, 2 days in a row (tourist). I went through a DHS checkpoint twice where they checked my ID and asked detailed questions about where I was going and why. The second day they wanted to know why I had gone two days in a row. There are (where back then anyway) big barriers they would lower to close a portion of the highway during 'missile' tests.

A fascinating place to visit.
