within any Giant Redwood forest...
or my grandmas house.
There already are a few.
The oldest and best IMO would be the Redwood Curtain, here in Arcata. College of the Redwoods in Eureka also plays through the redwoods on about half the course. Black Mouse in Felton plays through a redwood forest too. A few holes of Tarwater play through a redwood grove around the bottom of the course. There is also a private course that I know of up here that plays through a redwood forest, but it isn't listed on here.
