Not to be indelicate--but what are all those people doing about....mmmmmm....potty breaks? Do they have porta-potties up and down the freeways? Just curious.
Let it all hang out????
Getting out of their cars and walking to convenience stores, gas stations, any store that is open. The stores are being cooperative and letting them use the facilities. Walking to those kinds of stores usually means walking across the service road/feeder.
If you ever want to see capitalism at work just drive down a Houston freeway. There are stores of every kind one after the other.
The corner closest to my house has a convenience store on each quadrant. Four convenience stores all across the street from each other. They all make money. :-)
