Right, exactly. SF has kinda deceptively faraway CTA links. Arlington Heights has none. Plus it is not right off the highway. It's right off 53, but that's different.
And it's not an already developed area at all. It's like Ryan Field out there, you're in a John Hughes movie a football's throw away from the property in every direction. That's nothing like Jerry World in Arlington.
Foxborough is the best comparison in terms of the facility's isolation from its metro area. But New England is weird (it's far from Boston, but closer to Providence, Worcester, Hartford, what have you. Chicagoland isn't like that) and that stadium is hardly a rip-roaring success. A dome will do better, but still.
I don't feel super strongly that it's some disaster waiting to happen, but I'm skeptical.
(As a Crystal Lake native and longtime Metra NW line rider, I am also of course upset this didn't happen when I was a Bears-obsessed kid)
