chicago.a view from metro

if u’ve never been to chicago u probably don’t know enough about its metro. for me it was surprising that chicago metro has three levels:under, on and above the ground. and while going somewhere by metro u won’t see only dark tunnels. what u can see? chicago is not only the second business center of america, it’s also a calm peaceful place and sometimes u just won’t to ride by metro and stare at the window the whole architecture within arm’s finger. hope u’ll enjoy
