Great looking track. Well done.
Two bits of advice though: repaint that guitar, or it will give you a headache, and stop drinking Budwieser, it's the beer equivalent of Lambrini!
What make is the 906? Mine's a Fly and I think they've put tractor tyres on it by mistake - handles like a wheelbarrow with a slow puncture. When I've got time, I'm going to make some much lower profile urethanes for it. I'll gladly send you a pair to try if you want (no charge, as long as you promise to try weaning yourself off Bud).
Have a great time blasting around over christmas
