Portable light post made with PVC pipe! While this one probably isn't a geocache, it would be a cool idea to put a mini light post out in the middle of the woods as a cache. A bit like the lamp post in Narnia.
how to build a shed... This is a neat site and really is do-able... only you can't live in it, which is my main goal in building something. You have to be careful about your areas specs on livable housing. There are so many rules and regs. now grrr
PVC Light pole: Take 3" toilet flange for the base, 3" to a 2" reducer, 2" piece of pipe for what ever height you choose, a pole mount light fixture, a 3 wire extention cord (male plug on one end) and wire the other into the light. If you want to have a flag or sign on your light, you can use a 2" T with a 2" to a 1" reducer, then a short piece of 1" pipe with a cap. Before you paint it, use sandpaper to rough up the surface. We use tent stakes to anchor it to keep it from falling over.
