My wife and I are joining her family on vacation in DC this coming week a dim taking a bike along for some me time. I'm most likely taking my 77 Centurion semi-pro s/s. DC looks s/s friendly but I have other bikes if you think they'd might be more appropriate. Any route suggestions/places to avoid/places to go etc? We are staying on 13th st in Columbia heights if that helps. I've never been to DC for any extended period of time and I'm looking forward to this!
