you said you wanted to stop by and see it?
your UPS employee ID will get you inside UPS buildings, so if you wanted to go to CACH you could and see the operation (if that sorta thing gets your rocks off)...
But Louisville?!!
You need an AIRPORT ID BADGE for Louisville. You will need to comply with SIDA rules and if you do not show that badge that must be above your waist and below your neck at all times, you will be challenged.
Basically... you ain't gettin' on property.
