Going deeper, there is actually an unbuilt area SE of Lot 56A, where the hammer and discus throwers practice away from Toomey. This is a prime spot to park some vehicles, though access may need to be enhanced.
With the builds on the north side of the Pavilion over the last 10-15 years, the ICA field space is a little sacred, however, tailgaters would be temporary. Still cars driving on grass will have an effect on the field quality for sports surface for the students.
I want to see who Doss lands as an agent. Senior Bowl guys have a way of climbing high in the draft...teams are more comfortable with a kid (especially QB's) after a week of camp.
