I don't live in Wichita, but I don't think you will be bored there, unless you want to be. Many of my relatives live in Kansas, and they always are busy doing things. I spent a week in Wichita when my mother was in the hospital there and I liked it. It has been several years, but there were several places to buy fabric and lots of places to eat. I didn't have much time to shop, but there were stores all over the place.
I think you will enjoy it, especially since your son is there.
