First trip except for business. Trying not to look too much like a tourist - although probably a lost cause. Except for a couple of dinners where jacket/slacks (presume no ties) seem to be required - planning on jeans, black sneakers/walking shores, dark polo shirts and wind breakers. One day there is a long "rigorous" bike ride. Suggestions? Jeans seem inappropriate - shorts or hiking pants with zippered lower section that can be removed?
