Apparently, we simply never drove far enough.
If I could recommend you any town in Indiana, my recommendation would be Elkhart. Go to Elkhart. It's got a cool, historic downtown, a Botanical garden, a really pretty amazing Environmental Center, and... The Hall of Heroes.
We ended up in Elkhart, entirely by chance. We had, in fact, not intended to stop anywhere at all today, and, instead, just drive straight through to Youngston, OH. But, at one of the rest stops, I picked up a tourist brochure which had been organized by "stops along I-80." Shawn read to me in the car and when she hit the Hall of Heroes, I was like, "WAIT. There's a comic book and superhero museum and it's only about a minute off the main highway???"
Of course, we had to go.
The only problem was that it didn't open until 11:00 am. We arrived in Elkhart at 10:20 am. We could have just sat outside the shop? But, we would have been staring at this rather unimpressive storefront for a half hour:

So, Shawn flipped through our little tourism guide and discovered that there was a Botanical Garden just down Main Street. We found that, stopped in, but even though it looked like it might be quite nice, we were a bit put off by the sign that said that free admission was only for people who could PROVE residence in Elkhart County. I inquired within to see if we were BARRED or if we just had to pay, and it turns out we could have gotten in for $10 a piece. We decided, instead, to hop back in the car and check out the free Environmental Center further down the road.
What a good choice.

We wandered around through a wetland (saw a number of baby ducklings with their mama) and through an open prairie (and watched purple martins flit into their houses.) The trails near the Interpretative Center were very short loops and so perfect for a quick stretch and stroll, while we waited for the superhero museum to open.
A train stopped us for a short time, but we made it back to the Hall of Heroes around 11:30 am. We were the only people in the museum and so the guy behind the counter, John, gave us a personal tour. He asked us if we were fans of the movies or comics, and I was able to tell him that I grew up reading my cousin's father's comic books, which he'd started collecting almost from the moment comics were published, so I'd grown up on Jack Kirby and Stan Lee. Shawn came to comics from a slightly different angle, having loved all the Strange Tales and horror comic books. We collected comics together all through college, and then, of course, became fans of the MCU.
John was THRILLED and so very carefully pointed out all the cool draft sheets and inked pages they had on display, like this early Kirby art:

JACK KIRBY'S ART!!!!!!
Shawn and I spend a good hour at the museum, even pausing to play Deadpool pinball for awhile.
Man, what a find!
That was all we did today, but tomorrow, it's the Pennsylvania Wilds. I should have a lot more to share. And, because I've been listening to books on tape, I'll even have some things to report for "What Are You Reading Wednesday."
Hope you all are having a good week without me!
