I figure most of the people here are kids who have never seen a naked woman in their life. Why shouldn't people have a clean party, around here there are more clean bachelor parties than ones with naked women. My buddy went to one where the groom had sex with one of the strippers. In general it's a total lack of respect to the bride, especially since most guys who go to bachelor parties don't usually go to the strippers so why all of a sudden do you need naked women dancing for you?
You could always do something like going camping a weekend, whitewater rafting, parachuting. Rent a cabin somewhere and go fishing. How about just hitting the casino for a night of gambling?
