Help me with my roadtrip! Driving through NE, KS, OK, and TX

[mitch_04]

My wife and I are driving from Platte, SD to Seabrook, TX in mid-March of 2014. She and I are doing a half-marathon on Saturday the 15th and I'm also doing the full marathon on Sunday the 16th. We plan leaving the Tuesday before and and coming home the Tuesday after. We are going to take our time on the way down, turn it into a 3 day trip. We both love small towns and rural areas (probably since we are from both) and things like abandoned churches, schools, buildings, etc etc. I plan on taking highways on the way down, the Google maps below is just what it chooses and the actual route will be somewhat random and chosen on the way.

I'm looking for anyone that lives near my route to help me by recommending stops along the way. Great restaurants, interesting attractions, neat museums, dive bars, hole-in-the-walls, etc etc. I'm trying to not go out of the way more than 50 or so miles, but if it really seems interesting I'm sure I could make do. Since most locals tend to know the best places, I'm hoping some of you live or have lived near my route.

I appreciate the help!

You won't want to pass up this museum. You will be impressed. It is in Lincoln, NE. Here is a link:

Someone else recommended that to me, I looked at the link and it looks pretty amazing! I'm sure I'll leave depressed though, so many neat things and nothing for sale...as if I'd have the money anyways!
