This would also prevent third party vendors from selling alcohol at parties. This would also include all rooms in the fraternity house. I do have some concerns though.
Most fraternity houses are within walking distance of all the dorms.
In addition most have enough space for people to crash even if they do not live there. Although Sigma Nu nationals would have less liability for a party off campus at a private residence, the members of a chapter would still probably have as much liability. But instead of walking to the party, people would often have to drive. If we start moving all of our larger parties off campus, we will probably have to deal with a lot more drinking and driving. Many people have stated the fact that we did not sign Sigma Nu to drink.
