Not sure if it's too late, but I would also be interested in trading to C5 from C4.
Myself and my neighbor have passes for C5, but my in-laws were moved to C4 this year. Not only that, but my mother-in-law is battling cancer. Right now we're tailgating at the back of C5, so we are close to their car in C4. Moving them to C5 would allow us to get closer to Jack Trice. When you're pushing a wheelchair, every foot counts! If anyone else would like to trade, please let me know. I would even consider some boot to entice the trade!
Thanks!
