GREAT culvert jump idea! Put it over a pole, nail pole to posts, there you go!
Cool cross country jump! I think this could be easily done by drilling big holes in a fallen log or even 4x4, then bundling cut grasses (I'd wrap the bases with floral wire) and inserting into the holes.

We constructed this trail class training bridge for less than $50. It meets the minimum standard of 36" wide and is 8' long (6' minimum).
Open and close the 'gate' on horseback I want to work on this with Lacey, but we need to work on the basics first.
