Here is a tip for installing tiki lights in your yard. Cut a piece of 1" pvc pipe about 24" long. Cut one end on a diagonal and spray paint the whole thing black. Use a sledge hammer and a piece of wood over the pipe (so you don't damage the pipe and disperse the pressure) and hammer the pipe in. Then stick the tiki light in and you're done. It is also easy to take the torches down for inclement weather.
