I think you should (throw up, I mean). This really is too bad. We have always had our ride on the 3rd Saturday of April. It wasn't on the 14th last year - maybe the 16th or 17th.
All we could go by was the website...and it had listed April 14th or 15th...I can't remember now. We now understand that was an old date. Since folks have already started to register for your event, we have changed our date.
