So, I ran my first LSR, had no real issues, (other than a dead battery), made passes of 117, 128, 150 and 175 to earn my licenses and got the B CGC record. My first pass was the first time I had ever driven this car since building it. I put it on the trailer in Michigan and put it in tech then in staging. I was really happy with my weekend! 
  About the 1/2 mile..Will we use the same starting point? 1/2 mile feels a bit more like a drag race and traction early will be more important in trying to reach top speed. Can we not start on the paint?

From what i understand the starting point will be where the drivers meeting took place Saturday morning around the pickup truck. Just across form the sign in trailer etc. Staging I gather will be on the runway just to the left of that location. The 1/2 mile distance will then be timed at the same finish line location used for the full mile runs.
   Should be a fun time a bit shorter in length to get up to speed but with a gear change and a bit of traction fast runs are possible.  cheers

thanks for that, will we be able to heat the tires?

For the mile runs as you know no burnuts are allowed I would think that would also be the case for the half mile runs but Im not sure. Consdiering how the concrete runway is groved for rain run off I think that would damage the tires doing a burnout.  undecided

If trying to attract drag cars, street racers, sport bike's, outlaw farmtrucks or murderous nova's, I think a burnout box will be necessary.  I do not need to heat the tires to go fast but I do think over all it might be safer to allow a quick burnout behind the starting line rather than doing a 150 foot burnout during the timed pass..

Wow, a burnout box.  Hadn't thought of that.

Would a drag car really need to launch that hard for a 1/2 mile?  I'd think it would be wiser and safer to just hook up and smoothly lean into it.

As many cars that I saw trying to make hard launches for the mile, I can only imagine the enthusiastic starts for a 1/2 mile course.  My guess is there will be plenty of video opportunities that weekend.

You need to get to the drags more often, Chris! Heating the tires via a burnout is a huge factor in having them "hook up" during the actual run.

Jack, have you walked on a dragstrip lately.... hope you had your shoe laces tight....  rolleyes
My guess is they are not going to spray the runway with VHT... like the dragstrips

They do have stuff you can spray on your tires to make them softer and bite better but as the drag racers learned you don't go as fast smoking the tires as you do without tire spin.  Doubt they will be giving 60 and 330 ft times...  grin

I'm pretty sure the runway is still used for planes, and the folks that run the place are kinda finicky about the condition of the surface - so I'd guess there will be NO burnouts. Clutch tuning and throttle modulation only Smiley

I would think that rubber would be built up where the air planes touch down.

That rubber may not match your tread width.

Checking on Google Maps one runway is decommissioned. I would assume that's the one used for racing. The number on the runway is "x"ed out indicating the runway is not in use.

As long as everyone is following the same procedure it shouldn't matter whether a burnout area is provided or not.

You are correct Pete, my mistake. Maybe the new owners are more open to burnouts, but I know Joe Timney did not approve.

The no burnouts was for concern that there wasn't any way to protect the people and vehicles behind the starting line. Ohio has a very rough concrete with rain grooves running across the track...it would never really build up with rubber.
