I'm thinking of building a 2d Ray tree 2.5m high x 12 across so I can just cut a strip in half. I have been thinking of ideas that wouldn't require me digging and concreting and it being temporary. I was thinking of using a portable basketball post. Something like this http://pages.ebay.com/link/?nav=item.view&alt=web&id=161705755381 The base is filled with 215l of water and if my marys is correct that's 215kg of dead weight. (Lol) Has anyone else used something like this. Keep in mind it's a 2.5m tree and maybe a star on top.
