Good morning Milhouse and Happy Friday!
Sounds like you and Dad have some great memories in The Shoe and those are priceless for sure!
As far as your current dilemma, it is one I believe we all can share on some level because who wouldn't want to get back to Columbus for EVERY home game but life gets in the way and we are left to make choices.
So here's my $.02:
If you're looking for an early season match up, Cincinnati has to be the one. Luke Fickell back in The Shoe as the opposing HC has more back story than The Walking Dead...
If you're looking for that "marquee match up" than MSU, Wiscy or PSU may scratch that itch.
As noted by ATLBuckeye09 though, while PSU has been an absolute nail-biter the last two years, it looks like they're taking a step back so it may not live up to the hype. MSU is one of those games where you just never know. The last time they were in Columbus they got shellacked so they may some payback on their mind this time around. Wiscy looks like they could contend for the B1G West so that should be a great match up too.
In the event that you're in the mood for a road trip outside of Columbus, the Northwestern game looks like it could be a great one too!
The best news I can give you is you can't go wrong coming back for any of the games in The Shoe but I'd probably recommend the Wiscy game of the three marquee match ups in Columbus this year.
For what it's worth.
