Nope. No "special event." There are the usual other options: 25s, 50s, Lewis, yardage purse, jackpot purse, etc. But no SE. There was also added money. $1,400 to the Champion down to $200 for 14th through 20th place.
Still, a lone score at the top could pull in around $20 - 30k. Provided they played all the options, of course.
