Geocacher prompts terrorist fears for hiding bucket

I have thought of this when Geocaching. Do I seem shady? My pics on the side you can tell me. Even though I dont own a gun I might be able to pass as a extremist if I had a T-shirt that said something like "YOU CAN HAVE MY GUN, when you pry it from my paranoid, mentally disturbed, physically-abusive, cold, dead hands"
What do the Police think I'm doing.? Afterall I just pulled an Ammo case out from behind some Rocks.
