I'd have to get the addresses and go to Google maps, I've stayed in Golden and the park was directly below a steep section of highway what ran down to a stop light . Engine brakes all night.
EDIT: How does that saying go ?? I'll be back !
Made it back in time to edit again .
Whispering Spruce was where I stayed .
Golden Municipal , being just across the river, from Spruce , could be just as noisy.
Golden Golf Club , is far enough away from the hill that there shouldn't be too much highway noise; and from the online photos . It would be my pick.
