First, swimmers will need to stay very well hydrated this weekend. Temps are projected to pass the century mark. Parents, please take good care of yourselves as well.
Anyone wishing to do the open water event Sunday is welcome to enter. Brian has reminded me that any swimmer (A, BB, B, C) may swim the event. Also, there will not be a late entry surcharge if you'd like to deck-enter the open water event.
Meet info is here.
