I saw on Kool TVs Facebook that their channel is now available for Arvig cable customers. I'm not that familiar with Arvig but they list the following cities as having offices in Minnesota.

Detroit Lakes
Walker
Wabasso (south east Minnesota)
Twin Valley
Sauk Centre
Perham
Pelican Rapids
Parkers Prairie
Park Rapids
Melrose
Henning
Grand Meadow (southeast)
Bigfork
Bemidji
Battle Lake
Ada

North Dakota
Bismarck, grand forks, Fargo

Here's the current TV coverage map. Do we see any new TV markets we will be in? I know the SE Minnesota would be new. I think Walker and Sauk Centre would be new. Bemidji looks like it might be in there. Maybe Park Rapids.
