Chuck,

First I must apologize to you for the inadvertant information I posted in response to your problem. I put in .96 and .94 as drag factors. They should read .76 and .74 respectively. Thanks to Jim Mitchell I re-read the post ad saw the mistake. I hope that this hasn't caused you any inconvenience. The asphalt type was ID topcoat. Jim did think that I was measuring coral reef with that high number and I saw why after checking the post. Thanks for checking me Jim! I also went back to the site today and checked with the sled again and got a .71. This is six weeks later at about 95 degrees on a road with approx. 5,000 vehicles per day. Hoope this can help!
