April is April and anything could happen. I didn't take the time to compare schedules but some times just a couple weeks of time passing can make a huge difference weather wise. Could this show remain on the schedule but just be put two or so weeks later? April still has three weekends left, i know Easter is one of them but good Friday is a day off for a lot of people and is a good time to hit a race without using a day of vacation. Just an opinion.
