Due to construction delays, and uncertain weather conditions, they have
delayed the opening of the track for at least a week............so I'll have
to wait until I can go later on this month or next month......
On the air pressure issue, the local city government saw fit last Fall to
repave the alley outside my shop!........
Nice and smooth and clean surface......so I have managed to lay down a few
black marks of my own out back.........the pattern has been dark in the
middle and lighter toward the edges, so I think I'm gonna drop the air
by 2-3 lbs and see how some new marks look!!
Muhahahahahahahaha.........
