If you are that close, you should try to get to Miles City,Mt.
It is very worthwhile--(plus no sales tax in Mt. :wink: ) And there are 2 stores there:
Miles City Saddlery and Murdoch's Ranch and Home for a good boot selection.
I only know of one boot place in Glendive, Ranch and Farm Ace (that
is a fun store, they have lots of neat things.)
In Dickinson, ND there is
Wanner Western Wear. There used to be Corral West, but
I can't find it in the phone book, so perhaps it is no longer open.
I don't know much about further east or north, but I bet Minot has something. I don't have that phone book, or I'd look it up
for you.
Hope this helps! Good luck!
