LOL MD...just a thought...

They are expensive to hire. I think that flinging a house up onto the hill probably would cause it to fall. :D

looks like they could easily attach a house to it and fling it on the hill across the lake...lol...i had no idea they were so quickly set up and dismantled..

Trix, what's with this worrying about things that very likely won't happen? You've not been taking doom and gloom lessons???   LOL

If you look at the stills, it is being used. These things can be erected and dismantled in a couple of days. My son rents them out.

i just thought it looked kind of permanent...it's not really doing anything ...and i don't see anything being built...BUT...it could easily fall and kill many...

Trix, see how easy that was??? I gave you a one word answer. If someone wasn't annoyed with us, you could have had the long version involving multiple comments of varying lengths that would blind you with science. Now here's a picture.  :D
