We bought the black jump awhile ago for Jame's rc truck. The boys decided that they wanted to try jumping off of it. After a try the didn't like how high it was. They have been asking and asking us to buy the rest of the jump. James told them when he was their age he took scrap pieces of wood and made one himself. One day after school  Parker was begging me to make one so I agreed but when he found out that he didn't have to nail or screw it he didn't want to and wanted to wait for dad. I convinced him to come and make one with me and he hasn't stopped jumping since. They have been trying different heights to see which they like best. A few days later the boys decided  to make the ramp but have the black jump behind it act as a ramp. We told them it wont work and have the black jump first then the jump after.
