I'm glad you got your camera back but I wouldn't have moved the blind. Around here if your caught messing with someones stuff it could get real ugly.Regardless if they are a thief or not. A note would have made him/her think about it. Think about it, you feel you did not steal his blind by just moving it. Technically, didn't he just do the same? Point is don't lower yourself to his/her level. Be the better man.
Make a steel box for your camera and it will make it harder to steal. Also cuddyback's are pass word protected and gives you a little better feeling knowing that they can't use it.
Now, if you catch them in the act, kick their a**!
