A little OT but it is a funny story.....sorry for the hijack.
I think those deer things are not worth their weight in lead. In my experience the deer will learn nothing will happen. At least ours around her will. When we first moved in the wife wanted tulips....so did the deer. I would run out and scare them away, then they actually got to the point where I was just outside of arm length away and they would run. Then I started chucking ice cubes at them....then they figured out IF I hit them it really did not hurt so they would still stay and much away. Then I actually went and bought a red rider bb gun. That would make them run just out of range....I would chase them at 10 yard intervals across the field...as soon as I was gone they would come back. Then I went out with a real gun...shot it (into the ground) that made them run off...about 100 yards, they then turned around to say you can't shoot for **** can you.
I also tried soap, taking a wiz on the flowers, and lastly fishing string....nothing worked.
Yea I could kill it, but I really did not want to kill it, I just wanted them to leave, almost hit one on the way to work today....I really hate deer.
You want to know how I finally solved the problem.....the wife planted Daffodil's.
