My parents took us kids on a driving trip from Houston to Monterrey and Mexico City. Drove home along the gulf coast.
early 1970’s.
Picture that.
Never went to MC, but went to Monterry long time ago with second wife. Visited one of the original Pollo Regios. Got half a bird, an onion, beans, tortillas chips and hot sauce...cost like 2 bucks back in 2002
