When Scrooge McDuck's railroad men turn up at Grandma Duck's Farm insisting that she let his company's newest railroad cross her farmland, Duckburg's most formidable old lady is quick to tell Scrooge to stuff it. Scrooge, however, takes it as a challenge, and a battle of dirty tricks commence between the two stubborn old foxes!
- All the land directly around Grandma Duck's Farm apparently belongs to the government until the events of the story, when Scrooge McDuck buys it all through the Land Office in an effort to get Grandma to back down.
- Grandma notes that she has been using road leading out of her farmland and into the city] “for fifty years”.
- In his mental monologue, Scrooge acknowledges Grandma Duck as “the stubbornest person in the world except for [himself”. When he believes he's gained the upper hand, he also notes that “this will make the first time anyone ever bested her”.
- Scrooge displays the ability to drive a train engine.
- At various point in the story, Gus Goose addresses Grandma Duck as “mum” and as “granny,” making his place in the Duck family tree muddier than ever.
- Although this was likely coincidental, Don Rosa's The Invader of Fort Duckburg presented Elvira Duck as having principally lived on a different farm from her modern one in 1902, only later moving to the one on the outskirts of Duckburg following the transformation of the area around Killmotor Hill into the Duckburg metropolis's city centre. This is consistent to the year with her assertion in the 1952 story that she has “been using the road [between her modern farm and the city] for 50 years”.
