DirtFest at Raystown Lake, PA May 19-22

Does/has anyone here ever gone to DirtFest? How is it? I hear from some of my friends that are into mountain biking that they have some muni events there. Sadly I can’t make it because I was thinking it was in June, but is it worth going to in the future? I’ve lived in PA most of my life and never heard of it until I left, but I’m close enough to make a trip back if it’s worth my time.
