Great idea for a large back yard: Use your solar lights. They aren't just for the ground! Take a 2x4 and cut them into squares to fit the existing fence posts. Using galvanized screws - not nails - to screw a "L" bracket to the underneath base. Then on top, screw on the stake.
House smelling weird? Put two caps full of vanilla extract in a coffee cup, then place it in the oven at 300 degrees for one hour. Within twenty minutes the whole house smells like Heaven. It's actually a common realtor trick.
