My dd is buried in a military cemetary, they have certain rules. I do know that before bigger holidays, such as memorial day, they do a lot of mowing and cleaning up so that they can put up the flags etc.
I remember in the first year my dd was buried there I would go out there every Monday and put flowers out. I would go out wed and they would be gone. I was SOOO sure someone was stealing her flowers and I was soo mad. Turns out the deer were eating the flowers and the maintenance team came along and threw away the stems. I laughed at myself over that one. I could only imagine how the poor lady at the office felt. I was standing in front of her in tears explaining that SOMEONE was stealing flowers and do they have camera's. That poor woman had to explain the deer thing to me as I stood there crying! Later I realized what an idiot I was!
So, it 'could' be a deer issue! If someone is stealing them...karma. You can't get away from it!
