most of the dropin is made out of my old picnic table so that didnt cost too much. also the rail and jump are built with wood from around my house. i spent $30 on the metal pipes, $15 on the astroturf, $10 on the little wood that i didnt already have and $15 on the green plastic fence, which really isnt necessary but i just used it cause i bought it last summer. so total price $70.
