Those hitch chairs sure woulda been nice to have in the days of drive-in theatres. I remember families driving into the slots backwards in their pick-ups and sitting in the beds with their folding chairs.
What do you mean, "...in the days of...?" We have a drive-in theatre here and we fill the truck with friends and go at least twice a month. The movies (double feature) change every week and it's $6.00 a carload (it was $5.00 until last year). We put a mattress in the back of the truck and lots of pillow and blankets. We back in and the kids usually sit in the back of the truck and we adults sit in folding chairs in front of the tailgate. The drive-in opens early this year, Feb. 29th, and if the movie is supposed to be even halfway decent we'll be there!
