Derby Festival runs from April 15 thru May 2, and Derby Day is May 4. If we rule out this period, then we are left with two weekends in April (Saturdays, April 6 and 13) and three weekends in May (Saturdays May 13, 20, & 27).
(I saw the call for papers for Code PaLOUsa today and this was the first I had heard of the dates for the event: April 25-27. (Interestingly, this is during the Derby Festival! And they will be meeting at the downtown Marriott!))
