build a jib 101. but find a good hill around your house. get some green turf if its dirt and rocks underneath and use some orange safety netting. (orange safety netting only if theres grass underneath) some storage crates (like the ones at home depot) do well if you stack them then just make a ramp down it. make a lip which you can just use more crates or actually make one out of wood (thats what i did because its more stable) then just make the rails. rails are easy and should take a hour or two. just make a rectangular frame with slots in between. make some legs and screw some pvc on the top (i like doing two, one on each side rather than lets say 4 stacked close together because it makes it faster) then get just connect the legs to the frame (using small pieces of wood, which ends up looking like a v) to make sure it doesnt wobble sideways. then your good to go, just get some water and start jibbing. Good Luck or should I say Happy Jibbing!
