The field was a little tricky to find. Don't bother with mapquest or google maps. Call and get directions.
7 of us went to Iowa Paintball Park for a bachelors party. For most of us, it was our first time. Matt (the owner) and his employee were both very safety cautious and stressed safety throughout the day. The fields were great for a small group. We played for several hours for only $25 a piece. The put us through a variety of games, all of which were very fun.
During the actual games, Matt and his employee served as patient and helpful referees, depsite me shooting him in the back during one of the games. The games lasted about 10 minutes each, with rest periods in-between.
The only downside was the fact that the paintballs didn't always break upon hitting the target. Since this was my first time, I can't say whether or not it was normal. There was also periodic problems with the rental equipment throughout the day, but Matt and his guys were very quick on the repairs. They provide all the safety equipment, as well as cleaning supplies.
Overall, it was a great time and I would certainly consider going again.
Oh yeah - make sure you take bug spray and some bottled water.
