#17 - The Retired Gun is when we originally see the Feed and Grain - Wes Carney - Prop.
Wes and Clare Carney moved to Bolton City at the end of The Retired Gun
Looks like they never sold the store or they never changed the name.....
That "Wes Carney - Prop" sign can be seen six episodes later in The Silent Knife. Thanks Greg Merrill!
After I got Greg's email I started think about this and I also remembered seeing this sign in The Silent Knife ― Miss Bertie ― The Coward and counting.
Here is two other pictures of the Feed and Grain Store.
