Watch your things closely. Keep an eye out over the coming days. Sounds very much like he was casing your place. A home security system with HD cameras is a wise investment in your future. They are on sale at costco. You have things that people want. Be ready, willing, and able to protect them within the boundaries of the law. Best of luck to you. I've had so many things stolen from me over the years. I despise thieves in all forms. God help the one I catch.
