Fresh off a reprieve from existence thanks to Bryant Park and the New York Public Library, 41st St continues it's midtown march as you walk west from 6th Avenue. While the block is lined with plenty of throwaway stores, if you turn your attention upward you can see some really great architectural goodies floating around.
Making your trek past Broadway, you can catch glimpses of Times Square to the north, and the looming Port Authority Bus Terminal to the west. This being midtown, there aren't really and buildings under 10 stories, so there isn't much sunlight to go around. You're more likely to get a tan from one of the illuminated billboards in the area.
