This was created for a theme on flickr (www.flickr.com/photos/grandpappy), and I realized that people here might not have seen it. Here's the back story:
Old Man's Folly's has been in the league from many years. The same can also be said for it's driver, Samual Reedus, who has been driving Old's Man Folly since it's initial debut (then called "The Grinder"). The dual engines in the rear "tread-hub" provide enormous power to the single tread that runs the length of Old Man's Folly, and the reinforced cockpit provides a relatively safe (if not cramped) ride.
In the design stages, the engineers could never figure out how to get the cockpit to open while the tread was on the vehicle. To help combat this obvious safety issue, special treads were made for Old Man's Folly; each individual tread is fitted with explosive bolts, allowing for rapid untreading of the vehicle, and access to the cockpit. This works in theory.
Even the possibility of being unable to get out of the cockpit when an incident occurred (and they do) was an instant turn off for many potential pilots. But not for Reedus; he long ago stopped worrying about his safely, believing himself immortal.
To this day, armed with a powerful IATTAR racer, Sam Reedus continues to throw Old Man's Folly at the tracks. He even wins on occasion.

The tread is off, and the cockpit can open up
As you can see, two of the Power Miner "wheels" offer the perfect width for the tank tread. It does roll, but it has a click sound to it.

Oh alright. I've been working on a new mech too. It's another Izzo mech, but I have to wait for the Pick-A-Brick order to come, so I only posted a preview. I'm working to become as good as Izzo. You think you can post us a sneek peek at your project?

Hey, Nathan, Where've you been? You haven't posted a single new mech lately.
Just super busy. Work has been taking up a ton of my time lately.
I have something in the works, but it will be a while before I'm ready to post it. You can see my other recent Lego activity on my flickr page (www.flickr.com/photos/grandpappy)
I saw this on brickshelf awhile ago, and I'm glad I can comment on it now! I really like how you used the new wheels/drills with the tread, it's very innovative even if it makes it hard to get into the cockpit. The lights and grills on the sides compliment the design well.
Awesome tank/bike thing, I'm really a fan of your creations. I absolutly love futuristic racing things (be it hovercar, mech, bike, buggy, you name it) and this one is great. It's nice to see a little deviation from mechs every once in awhile. Keep on building ~ Nowhereman
This is a great creation as usual from you! nice and complicated techniques in this little thing... do you know what I like the most?! the technique for the mini fig seat! amazing solution for three wide space... keep on this great level and thanks for the feedback on my KITT :) >>> peace.. Fofo
