So, when we lived in the suburbs of Chicago I always brought at least two machines for the free play area and yes dealing with Mike P was enough to rattle even this guy's normally cool demeanor. But, since Andrew and everyone in the red shirts stepped in to manage the free play area, donating games became the enjoyable experience it should have always been.
Since we moved, I've still driven back the past two years and brought one pin (so as to avoid having to drag my trailer 1K miles each way) and we're planning to come back this year too, especially because since it is in Chicago there's so much more than just doing Expo. That said, I'll be really disappointed if the team managing the free play area isn't there this time. That would probably be the last nail in the coffin for us.
