What does every backyard need? A ZIPLINE! All the items were purchase at Home Depot for less than $100.
Garage door pulleys for the wheels and L brackets formed the trolley.
I then used carabiners to attach an old bike handle bar for the kids to hold onto.
A come-along winch is used to adjust the tension.
Add a bunch of kids and you have a ton of fun!
The wood helps keep the cables from cutting into the tree.
