Likely moving in the next year - what are some "must do" activities before that?

Hi! So like the title says, my family (F29, M28, M2) will most likely be moving out of Omaha in the next year.

We've been here for 5 years now already, so obvious things like the zoo, Vala's, museums have all been done. What are some things we might have missed but shouldn't leave without experiencing? Any hole in the wall restaurants, cute stores, fun weekend activities etc.
