I was out to check on a nearby cache and decided to place a couple while I was in the area.
I have to fly tomorrow and needed to check in today, so I'm looking for a place to drop a cache when my reminder alarm goes off, it was time to check in!
Gotta love technology, stood right here and got my boarding pass, so now there's a cache here to mark the check in spot!
You're looking for a 50 ml centrifuge tube.
