I just found out that one of our local NHRA tracks has live feed from the track. Everytime the tower enters info for the next race, it is automatically displayed on this website .

If you enter a driver name or number an alert sounds each time the driver lines up.
It may be old hat to you guys but pretty neet for me..If your track has this set up, how about posting a link??
