Based on my last trip from L.A. to Michigan via I-70. I-76 and I-80 last 
January, and numerous previous trips across the heartland:

Eastern Colorado, once out of range of digipeaters above Denver in the 
front range,  has no coverage at all.  

All of NB until you get to Lincoln-Omaha area is a black hole of 
non-coverage except for a small island around Kearny.

KS -  Activity in KC-Topeka -Wichita corridor; very little west of there 
until you get to Denver.

SD - Almost nothing except an island around  Sioux Falls

IA - Excellent modern WIDEn-N network covers nearly 100% of the 
Interstates and most other areas as well.

MO - Coverage along most interstates but very spotty in the hilly Ozark 
area in the west, and on secondary roads. 

WI and MN  good almost continuous coverage in the southern (i.e. more 
urbanized) part of both states.  Rather spotty in the northern parts 
(i.e. activity in Duluth, then very little until you get to Minneapolis 
metro area for example.)
