This has been a concept I have had for a long time, and is the basis of what we're doing on the Outer Log Loops: a log feature where there is dirt up, logs in the middle, and dirt down. You can optionally go slower and ride the logs, go faster and skim them, or pull up and jump them.
On the first one (at the beginning of Outer Log Loops), we spent one 3-hour Austin Ridge Rider work day cutting and gathering logs, then another ARR work day building it (Jan 19): https://www.facebook.com/permalink.php?story_fbid=467776887228151&id=278952176110624

We intend on making more upgrades (like more dirt on the right side of the logs to hold them solid. (The little dirt kicker that was added to the top left side was an unauthorized addition, and I've had several conversations with the guy who added it. I'm going to re-do it further to the left, but not tearing what he did down until that time).
There are also plans to improve the second one (after the 180 berm). So, basically, both will get upgraded to version 2.0. (The drawing says 3 feet tall, but right now, they're only about 2 feet tall). (The drawing has two features back-to-back, but on Outer Log, it's just a single feature.)
