Crazy Daves- Cheap paint, good fields
Three Rivers is one of the best rec ball places that I have ever played. All of their fields are of high quality, and are kept in top shape. They have multiple things over the year, like 3-man tourneys and mega games (they open up all the fields and you play over 60 acres), which are alot of fun. The refs and employees there are very knowledgable of the game, unlike some places ive been (cough, cough, combat zone), and it is a very safe field because of this. They have good rental guns (tippman 98c) and decent paint ,although it is VERY price, about 90 dollars a case, but that the paint is how they make their money. I would highly suggest going to this field, because it is of such high quality, despite the cost. They started the IAO, so, of course they know what they are doing. I'm giving it an 8, only because of the prices. If it wasn't for those, it would definently get a 10 in my book.
