I have a hat that has just a big Buckeye on the front and I also live in the Bay Area. I quit wearing the hat because I got tired of everyone thinking I was wearing a pot leaf hat. Last time I wore it was about a year ago. Tourist guy comes up to me, says he likes the hat and asks if I am excited for the upcoming fall. I say I am but we've got some questions to answer on offense and some big games to get past. He looks at me with a confused look and then asks, "So you think it won't pass?" ("it" being the full recreational bill on the November ballot that did end up passing). To which I become confused thinking he is making some strange reference to the passing game. We stand there awkwardly for a for moments during which he glances up at my hat a few times. I then say, "It's a Buckeye leaf." and turn the hat around to show "Ohio State Buckeyes" embroidered on the back. He then apologizes and walks away saying, "And I'm from Michigan, I should have known better."
I stick with my Block O hat these days.
