Veishea is the largest (and longest running, I do believe) student-run festival on college campuses across the campus. It first started so that the different colleges within Iowa state could show others what was happening within the college, like research, etc. (like a giant open house) Since then it has grown and become a showcase for the entire university--colleges, departments, student groups, alumni, etc etc. Alumni and their families traditionally come back every year, so Ames is packed with people for the big parade on the last weekend. It usually lasts a week, with activities and food on central campus for students and staff during the day and then activities throughout the week. Ames is quite the happening place during Veishea. This year (2005) it was cancelled, due to a riot the last night of last year's Veishea celebration. It was a pretty big deal in the ISU and Ames community, so it was cancelled this year, in order to make longer-term plans and considerations. It will happen again next year (sadly this is my senior year, and no Veishea). That's the long and the short of it. Oh there's a parade, booths all over campus, Open houses, food vendors, cherry pies (yummy) and LOTS of other stuff....:-)
The picture (while I need to replace it, but not now) is from Veishea 2001 when they made a HUGE rice krispy treat--largest in the world, in fact, in honor of the creator of the rice krispy treat--an alum of Iowa State!
