A group of us tried 3 back about 10-12 years ago. It was pretty tough. One property ended up getting the majority of the time. IMHO, it would be better to have multiple, shorter days than one really, really long day where folks start losing interest.
FTR...I'm about sick and tired of seeing those 4 letters too. Sheesh...for a bunch of guys who supposedly are frustrated with said organization, some of you sure like bringing them up ad nauseum.
