I flew into Cancun
dozens of times with boat
parts. Always had receipts for everything and a neatly printed summery. Always careful to stay under $300. Got the red light several times and handed them the summery with the original receipts stapled to it. Usually waved right on through. A couple of times they counted pieces and wanted to match up receipts to pieces. That was every time except once. I had a cast iron exhaust elbow
for a Ford Lehman engine
. I didn't even get to the "Push the Button". When the gal on the X-ray machine saw it she called over a supervisor and they wanted to see it. I showed it to them and the original receipt from American Diesel
(for $120) and he didn't believe that it only cost $120. I kept saying "Not Yanmar
. It's a Ford!" After a couple of long minutes he shook his head
and waved me through.
