It was expensive. I used to call it to find out who won the Top Alcohol classes. About 40% of the time, after listening to the pro results and being billed for being on the line, they didn't give any sportsman results.
I copied the idea for the motorcycle drag races. The promotor would fax me the results as soon as the last pair went down, and I would put it on the answering machine on a spare phone. People would be calling all night.
I don't think I ever dialed it back then. Since it was by the minute, did he talk real slow? Or did it start like with reading off Jr. Dragster, then all the sportsman classes and then the alcohol classes, then PSM, PS, FC and finally TF?? Or was there an option to only hear what you wanted?
