You can get everything u need at home depot (or menards). The astro turf is in the carpet sectioin of the store an you can get an 6 by 8 piece for 15 dollars (if u cut that in half it becomes 3 by 16 which is perfect for a drop in and ramp) At home depot find the pvc isle and get the 1 1/2 pipes ( each is like 2 bucks). Camp down the pipes on a board and drill holes up through the bottom and screw in screws. you need a screw about every 18 inches. Also, the drop in and ramp probably dont need to be as bigg as u originally thought. Hope this helps, if u have any more questions send me a message.
