Be sure to follow the rule before you head out.
Rule: You must post before you leave.
if your in the states chicago has that. City is on a grid system and up to two transfers between bus and trains are free not to mention the fare itself is very reasonable https://www.transitchicago.com/fares/ also bike lanes abound now. You would be hard pressed to find a major street without at least the lines and most expansion now is about protected lanes.
