If I was in the situation that the family from Swiss Family Robinson was in this would be an idea I have. No, it doesn’t really help me survive but this was all I could come up with. I think that if the family had more of a little tree house city instead of the one big tree house, they could use zip lines to get around. They could use rope for the line and heavy duty wooden suit hangers for getting around, they could twist the metal hook around so that it doesn’t pop off. They could use these zip lines to go from place to place in the mini tree house city thing, or go right onto the ground if they needed to go hunt for food. Like I had said this has nothing to do with helping them (or me if I were stuck in their position) survive but it would be a cool idea. It sounds fun even though I’m not one to do zip lining, going to water parks (I’m definitely not a water person I’ll drink but that’s it I won’t swim in it) tubing in the snow or water. I think I’ve made it clear I don’t like swimming. My point is I wouldn’t mind trying this zip line.
