Back in the early 80s I took a trip up North by air. My brother needed the front spindles and drums for his 66 Nova. While in Pennsylvania I ran across someone that was parting out a Nova. I bought the spindles and drums for only $50. I bought a used, cheap piece of luggage and packed all the parts for the trip back to S. Texas. Needless to say the luggage with all the parts was very heavy. I had to gingerly carry the large bag into the airport acting as if it wasn't that heavy (almost pulled my shoulder out). I placed the luggage on the ticket counter rack and almost busted out laughing when the skinny girl at the counter grabbed the bag and tried to move it behind the counter. She ended up pulling it off the luggage tray and dragging onto the conveyor belt. I felt bad about the poor girl's lack of strength but my brother really needed the parts for his car.
You could never do that in any of today's airports...LOL!!
