There is another thread about tickets being checked on some transportation systems which led to a discussion on free public transportation for seniors.
I'm headed back to Prague today where public transportation for those over 65 is free. I think back to my last trip and I tended to hop on a tram because it was free rather than walk the same distance.
So my question is this...if public transportation where you are going is free, would you tend to take it more than walk if both were available?
