No i haven't been to the Don jumps...
though I would be suspect of anything Dirt jumpish that locals built..... launching into trees sounds par for the course. I was looking more for some speedy air, nothing sick and vertical. Woop-di-doos maybe a lap bump, nothing sick that could kill. I'm far too old for that action.....lol
What attention would beers and/or blunts and a bunch of jackasses on bikes get in the night at the nice track?
