I had a blast at M-40 for a bachelor party last week. I have welts to prove it - so does the bachelor! They re-did the outdoor field it is lit-up with tons of barrels and tires - a well balanced and fair play field. The indoor field was very big and surprisingly clean!! The Refs were cool, they had original game ideas and were involved. We played outdoors, then it rained, so we ended the game indoors. M-40 gets a 10.
