It must have been nasty for the border patrol station to be closed.
15ish years ago on a trip back to AZ on Labor day weekend we encountered major storm cells between the border and Ajo.
It took us 2.5 hours to drive the 40 miles from the border to Ajo, we had to wait 1+ hours for the washes and more time to pull off the road
because of hydroplaning on the road due to the severe rain. I bet it rained 3+ inches in that stretch, my wipers couldn't work fast enough
in order to see 20 feet in front of the car I was driving.
