Holiday get-togethers are in full swing but after indulging in more than a few drinks, the last thing you want to do is squeeze yourself onto a crowded CTA bus or drop your last $20 on cab fare home. Miller Lite Free Rides picks up where being chauffeured by your mother left off: Starting tomorrow night from 8pm to midnight, and continuing every Saturday through December 26 (plus New Year’s Eve and New Year’s Day), the behemoth beer brand will offer free doubledecker bus service with stops in booze meccas such as the Loop, River North, Old Town, Lincoln Park and Wrigleyville. Miller says the free rides are intended to remind Chicago consumers to celebrate the season responsibly and to prevent drunk driving: We can raise a glass to that but there’s also much to be said for sequestering all the drunks on one big party vehicle. Let the sober folks have their lurching cabs and overstuffed buses.
