Very, very few places have FAT. I think Drake and State were the only times in four years I had FAT used.
Actually many places have FAT now and some of the ones that do not hire a timing company to come in that does have FAT. I can say that Ames, Ankeny, Nevada, Gilbert (timing company), FT Dodge, Grundy Center, Dike, Hudson, Waverly, Decorah, and many many others have FAT.
At $15,000 per system it is crazy but they have it. I would say this has happened over the last 3 years. I am not sure if it is the case this year but I know you will not be able to host districts unless you have FAT.
