Might be a bit outside your scope of interests, but the Early Ford V-8 Foundation Museum, just outside of Auburn, IN (straight up from Ft. Wayne) is a pretty cool place to visit. Lots of cool early flathead race pieces that are really unique to the early days of hotrodding. Stuff like dual plug heads with swirl inducing chambers....which people think were invented just yesterday. They also have one of the original all stainless Fords (a '36) that they produced. Also some really neat all original low mile cars. One, a '32 5 window, is one of the coolest all original cars I've seen.
I'm hoping to make the '26 Muncie meet again this year, but it's not looking good at this time. Made it to the 3rd round last year, just short of the money, but had a blast. Hopefully it'll be warmer this year.
