Yeah, that was block. Three or four fraternities and their partner sorority block at Joes and it's a toned down version of the 10x10 fiasco that happens down the street at Red Lion. I could see one or two of those Joes fraternities as well as some of the ones without block going to grange grove. But block is the social standard for fraternities and sororities on campus. Frankly, it will take one of the top four fraternities to take the leap from block to tailgating (as well as some relaxation by the IFC) for tailgating to really happen. Certainly not unreasonable, but I'd put the timeline at 3-5 years down the road for that to happen.
Okay, so it is actually pretty organized and a pretty big deal, the block. Like, it is "the thing to do" for greek life during the football season and since you only have to be 19 to get into the bars (and not drink, cough cough) they end up not leaving the bars even when the game starts?
