You can kill me but don’t spread my body parts across Interstate 380 on the way to Chicago.
Interstate 380 goes only as far as Iowa City, where it links to Interstate 80 which goes on to Chicago.
Of course he meant Interstate 380 southbound.
380 northbound goes to Waterloo IA.
Now depending whether they’re at the north end or south end of Cedar Rapids, that’s a 13-24 mile stretch of highway.
