what town is halfway between Chicago and Indianapolis?

I currently live in Upstate South Carolina near Clemson and it rceahed 71 degrees here yesterday, so it's pretty much warm all round, with the occasional cool day like today and tomorrow, but then back up in the 60 s again for the weekend. I have only lived here for a year, so not sure if this is normal or not. I have not had to use my heat yet here, which feels weird since it's January. I have even had to use my A/C a few days in December.References :
