Great idea for a 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.
I love this idea! It's made out of 2 x 4s. Not only is it way more affordable than buying but it can be sized to fit your space. I saw something similar in the Pottery Barn catalogue for thousands of dollars.
This pretty limestone fireplace brings the convienence of an indoor fireplace outside. More outdoor fireplaces: http://www.bhg.com/decorating/fireplace/outdoor/outdoor-fireplace-ideas/?socsrc=bhgpin060612
