Well, there are a lot of wild rabbits hopping around Denver so it must be good land for rabbits in general. This is certainly worth looking into some more.
My grandparents kept rabbits for food during the war year in Germany. Oma and Mom would go for a long walk when it was time for Opa to prepare a rabbit. If he didn't kill it with the first blow the sound it would make would it hard for them to eat it so that was why they went on the walk.
This certainly is worth more research.
