Kokomo also has two (2) malls located on US 31 and has numerous places to eat.
Just south of town on US 31 there is a go-kart and batting cage facility -- if you're heading North on US 31 heading into town it will be on the right-hand side near an Arby's, Subway, etc.
There are other places of interests...historical sites, parks, landmarks, etc.
