The stops along a second-line route are primarily places for the parading organization to show honor and respect to other organizations (and vice versa), but large crowds gather at these spots, many of which are traditionally-significant locations, so the intersections become sudden venues, at which dancers show off their creativity and skill and vendors sell their food, drinks or other products. Note the second-liner who is dancing on the roof of Joe’s House of Blues, Uptown New Orleans, 10/21/12
