March 4th seems kind of early to kick off the drive-in season.
I posted the Tower Drive-in's 1956 Grand Reopening ad here.
That's a pretty unusual double feature – Women's World (1954) and Siege at Red River (1954). Something for both sexes I guess.
If you've got the time (and some popcorn) you can watch Siege at Red River right now below, courtesy of YouTube. It stars Van Johnson and Joanne Dru, who was in another similarly named movie – Red River – with John Wayne.
Siege at Red River has some great artwork during the opening credits.
