I've been to the driving range a couple times back in high school, and I doubt SkyTrain'd be any louder than the traffic along Uni Boulevard. As for people who do find it ugly (

Seriously, if there's any reason to not build through empty woods, save a hundred mil or two and cheer up faculty/students on their way to school or home, it really should be an insurmountable engineering problem. Not a few easily-distracted golfers.
