Man, you don't realize how hard it is to find a cache to fit a TB of this size until you actually need one.
On a related note, why must people mark caches as 'regular' size when they're CLEARLY small?!? The geocaching page clearly says an 'ammo can' is an appropriate size to use the term 'regular' for. When like... 3 or 4 of your cache containers could fit in an ammo can, that is NOT a regular sized cache!
Same with Altoids tins... those are not 'small'... they're 'micro'.
The hunt shall continue! I may need to find one marked 'large' at this rate... but given recent finds, that'd probably be the size of a tupperware container that manages to be unable to hold a CD 😛.
