we decided to do what out hobby store did and put 55 gallon barrels inside our jumps to use less dirt. i found somebody who has 27 of them that i can have for free

. we figured we could put them inside the berms and jumps since we already have a 5 foot deep hole for one tabletop that is 1 1/2 feet tall[:'(]. we want a couple of jumps that are maybe 4 feet tall and maybe an even bigger one at the start/finish line.
has anybody else tried this?
