Most of Crown Point is not covered. From Merrilville into Crown Point, it works until you hit the Lake County Government building. From there until the hospital, you only get 3G. I haven't been able to make it past the hospital but I heard it works south of there and into Lowell. As far as the Gary signal, it startd about a half mile east of I-65 and US 12/20. So basically the answer to the miller question is no. I found it funny they didn't light miller up because one, ...it's a part of Gary, and two, it's the most populated (and largest income earning) area of Gary.
