The comments by PiscatawayMike, RUPete, and albanyknight are on point. My experiences at The Grove and SC's "World's Largest Cocktail Party" have left me quite unimpressed. Sure, there are groups that have their specialities like names for the tailgate or types of dishes that individuals bring in, but the majority have become nothing more than catered spaces. Meh. Everyone from a company to one of our Chartered Groups, to the everyday schmoe can get a tailgate catered if they wanted. Rutgers already has working relationships with Cedar Grove and Twin Oaks who can do setups on gameday in the lots as long as they can get to your site.
For me, the biggest change has been in the quality of the tailgates at RU. I can recall back into the 1970's and even through the late 1990's, the tailgates consisted of a couple of Tastee Subs and a six-pack from the corner liquor store on 27 and Plainfield Ave. before it became the billiards shop it is today. Today, you have much more prepared and detail-oriented tailgates. People are designated to bring certain items. Menus are discussed on Facebook through pages and direct messages of the group.
Having been one of the three/four who run Olde Queens Island in the Scarlet Lot for five years now, I can honestly say - irrespective of the lots I walk through - people who show up each gameday actually want to be there (well maybe not MrScrew). Beyond OQI, Friends of Frank, located in the Yellow Lot, and Sweet Lou's in Blue, are perfect examples of the much larger tailgates that are in place now. Another one is The Pickled Knights in Yellow and "The Chandeliers" in Scarlet.
Scarlet Pride, I would say a Grove-style atmosphere already exists within the individual lots. The difference is the atmosphere is somewhat distinctive lot-to-lot, but always Rutgers First. Just my observation.
