Way cool – I love it!
My first thoughts:
A driving range would be hell on earth for a rabbit, you would be everyone’s moving target. I bet that’s where the abandoned warren is located!
Also, the terror of running and trying to duck down a hole only to find out that it was meant for a golf ball and you are cornered.
What happens when you run through a sand trap?
What happens when they hold a golf tournament? The crowd’s polite golf clap must be terrifying!
If there were another population of animals, I bet the’d all be named after golf jargon.
A map of the course might be broken up into different golf holes. Is there a significance to the numbered flags, who can decipher their hidden meaning?
Are there aspects of golf that you can parallel in the themes of the setting? For example, classism, tradition, Scottish origins, etc.
