I used to live at 59th and Harper.
You can't get between those two points in 15 minutes, I agree.
But you can go down 79th to Cork and get on the tollway to Hinsdale. That's like 10 miles on 79th St. and like 5ish miles on the tollway.
That 10mi on 79th is bad unless you hit greens all the way.
Fair enough. Are you aware that the Hinsdale Metra Station isn't near the golf course you reference? That would add some more time. I didn't mean to get on you, but I was curious to see how you could do it. (Nickname: "navigator")
