This is by far the best field in Nebraska. The place is family owned and operated and the owner is really nice. Mad Cow has some of the cheapest prices around and they allow you to bring your own paint. The entry fee is $10.00 if you buy their paint, and $15.00 if you bring your own. A case of 2,000 paint is $45.00 and a bag of 500 is $12.00 (They use Karnage paint balls in case you were wondering). You can also rent equipment and markers. They are open from 10:00am until dark on Saturdays and 10:00am until 5:00pm Sundays. There were roughly six fields in operation the two times I went. There is a castle course, a trench course, a large woods ball course, two spool courses, and a speed ball course. The fields are always well maintained and well refed. If you are looking for a good field to play at and you don't want to spent 200 bucks every time you go, then I highly recommend Mad Cow.
