While some enthusiasts will march with as many schools as they can, most people march only with the school that they support and love. Passistas on the same ala often know each other, and this camaraderie shows on the runway. The interaction within the group and with the audience is a key element to a successful parade. Even if you don't know anyone, keep in mind that before marching you have to wait at the concentration for a good hour or two. Even when go on your own, you may end up making new friends.
