Eh, Wichita isn't a hellhole or anything. It's a pretty typical small to medium sized, boring, generic city(I think the population is a few hundred thousand, it's not tiny). Has all the typical stores and chain restaurants that you would expect, as well as a fairly large university. They have one of the worlds largest Imax theaters, a minor league hockey team and several museums.
I'd definitely never want to live there, but there are worse places to visit for a few days. Just FYI it'll be ass cold in the winter(down to below zero) and stupid hot in the summer(can get up over 100)
