Cecil, Meadowlark,
Thanks for the replies.
I'll be getting one or a few of these stealth cameras very soon.
I can't say for 100% certainty that my caretaker is not in on this thievery, however, my gut tells me he is not.
We are thinking of ways to secure the "new" slabs we put down. We're thinking about how we could use concrete.
The railroad berm is owned by CSX, and we can't stop traffic on it for now. It's the greatest source of trespasser's access to my pond & property.
I like the trap idea, however I'd probably get my own damn foot caught in the thing.
