We did stupid shit. Cinder block + plywood = ramp. Pile of tree limbs + plywood = ramp. 1x10's also work(have to focus a bit more on the approach). Lots of scrapes, pain, getting the wind knocked out of you only being able to mutter, "Don't touch me!" to your friends and thinking your parents are going to kill you if you broke anything. Wood, tools, and supplies cost money(limiting factor for most young people). There's always gonna be the "right" way and then there's something that might work and is within your reach. I admire that he's doing it.
Grammar: The difference between knowing your shit and knowing you're shit.
