I'm not sure. I know they redid the student parking for this school year into zones which I think has helped (

I think as Ole Miss grows everyone (students, professors, staff, alumni) will have to understand you might not be able to park close to your sorority house/dorm/classroom/office/etc. Unfortunately our growing pains are a good thing and it's just something we all need to deal with in strides.
I know as a staff member and sorority alumna, the parking on Rebel Drive has been awful since oh about 2008. Whenever I have something at the AOII house I have my husband drop me off or I just prepare to walk. The last time I was there I parked all the way down Rebel Drive near the Health Center. This weekend for Skit Preview I'll have my husband drop me off again.
