i'm getting ready for my 25 right now too. i am always one of 3 people that plan the whole damn thing, we have pretty tight class and all get along (except one banned dumarss) we have had a 5,10, 15, 20 yr reunions and all went smooth (except for my drinking)
we have 3 days of fun together drink golf & drink then go away for another 5 yrs, no problem
