Seems every other post I read about being in downtown Savannah after nightfall is full of perilous warnings. We're coming into town for our wedding/honeymoon and plan on doing lots of walking after dark.
We walk around Atlanta after dark without any issues, how can Savannah be any worse? There are unkind and unsavory people everywhere you go. You just have to know how to avoid them, or to not put yourself in a dangerous situation at all. I think it's key to not appear like a tourist, or out of place. Behave like you know your way around and you belong there and for the most part, trouble won't find you.
If walking from Broughton to River St and back again is such a bad idea after 10pm, tell me now and I'll be sure to call a pedicab.
