longstreet, out of virginia. so if virginians are going dominate the writing of civil war history and if robert e. lee is to be elevated to a kind of semidiety, somebody has to be blamed. and it can't be lee or the other virginians. for gettysburg am and longstreet in their eyes, also made the mistake after the war of becoming a republican, urging southern whites to accept the outcome of the war, accepting a federal office from grant when he was president. and becoming commander of the interracial pro reconstruction militia of louisiana in clashes, armed clashes with lots of people being killed with the so-called white leagues in louisiana who consisted primarily of confederate veterans. so they didn't like his politics, either. and i would say that down until -- there were some historians. a man named glen tucker who wrote a book called "lee and longstreet" back in the 1950's who took logstreet's side in that controversy and said if somebody's on the confederate side is responsible for mistakes at gettysburg, it

the longstreet's are highlighted on your screens as the yellow streaks moving parallel to the river,and even though each street has a different section, they all share the pattern of injury, and bay windows. it sounds a little bit like san francisco. the cross streets, they move from the river, and to the river, and the buildings engage the streets differently. along this street they are very few inches along the edge and if there is an entry, this is recessed. so when you are in there, you always know if you are moving parallel or perpendicular to the river. because this is so clear, the newer and the older buildings maintain this orientation. i think they have opportunities to increase their legibility. the main streets are associated with moving to and from the water, the number streets are associated with moving up and down the peninsula. how can this be made more legible. one opportunity is to look at the use of corners. these are sights that are vacant or have small buildings in the middle of a lot that is open. and so the corners are not directional. as soma changes, building
