In my recent Internet wanderings, I stumbled across a handy site that takes all the selecting screens out of CTA Bus Tracker.
Instead, you just go to the site, allow it to know your location, and it will tell you where the nearest buses are. And even if you don't want the app to know where you are, it's another alternative to Bus Tracker.
It seems like this would be most handy if you're somewhere that you don't usually frequent, and thus don't already have a bookmark set in your phone.
"A close bus" was created by Dylan Richard, and he says, "This is just a little handy site to find the closest bus to where you are in Chicago."
Check it out and let me know what you think.
