Why are people slow to switch to public transportation? Probably partly because agencies like Athens Transit do a poor job of staying consistent and communicating with their potential ridership. If you can't figure out how to find a bus, you probably won't ride one. I found the Saturday timetable for Route 20 online -- but it says nothing about how the route is slightly different on Saturdays. So I just stood outside for 25 minutes for nothing. And then their phone number to ask questions isn't on the website either. (It's 706 613-3430 in case you need to know.)
Update: The guides for routes 6 and 20 have NO MAPS, either in print or online. Thanks, Athens Transit, for ruining my Saturday.
