I just stumbled into this announcement:
...which outlines Purdue's plans to sell beer and wine inside Ross-Ade Stadium starting this fall. The sales will be limited to the new patio area which will be set up in the south end zone, replacing the rickety old bleachers which were very recently torn down.
Those are the same south bleachers which for years were primarily occupied by visiting fans, meaning that Purdue will likely now designate part of north end zone as the visitors seating area. Purdue is still working on plans for a major renovation at some point in the coming years, and those plans likely will include building a permanant addition to the stadium where the south bleachers used to be.
The new patio area will be limited to a maximum of 1500 fans at a time and will be also limited to season ticket holders and students who purchase a special pass. Beer and wine and "typical tailgate foods" will be sold in that area, making Ross-Ade only the 2nd B1G Football Stadium to allow alcohol sales.
