the wife wanted this thing for her (i don't know what the hell its called, its a tree of some sort with long tendrils that take over half the bleedin house each season and i have to hack back every fall) so now the octopus tree can roam freely over the top and be trimmed easily. now what if i were to bolt a bunch of posts (between the two uprights) sideways and fill with insulators???? you will see the results soon!
