I had a Travel Bug Hotel near here, and this cache is placed in memory of that hotel. I tried lock-n-locks, I tried Ammo Cans, I even tried a cinder block. Too bad they kept getting washed away.
This cache shouldn't have that much of a problem. You're looking for a micro (not a nano) and it'll probably be "eye high" depening on your eye height. Micro cache container with log only. Bring your own writing device. Please reseal tightly.
