This is the start of my Crawler course. I've got a bank that makes a 90° Turn and it's full of River Rock. Some med sized but lots of smaller ones. Med sized tree limbs about a foot or so long. I made kinda like a hill out of those big pieces of Wood (Not sure how that will work). Not sure how high to build my Rock piles. Y'all help me out throw out some ideas what you see is what I got to work with. The area all together is probably about 50ft long and the bank is probably about 8ft wide.
