I've been to KMC many times. If there is a popular act playing, it will be over-crowded. Large crowds and alcohol almost never mix well. There are almost always long lines for restrooms and concessions. Fans are rude and pushy on the lawn, so if you must go to KMC, I recommend paying the extra money for reserved pavillion seating. Once the concert is over, prepare for a long wait to get home. The traffic out of the parking lots and onto the surface streets surrounding the venue is terrible. There is not enough public infrastructure in the area to efficiently handle the volume of cars.
