Last time I saw Sally B was at Duxford's Flying Legends show, where there were also two other B-17s present (I know the French-owned 'Pink Lady' was one of them, can't remember the other one), but it was quite a sight to see three B-17s taxying on the same airfield at the same time. Technically, there were actually four on the airfield I suppose, if you include the one in the USAF Museum at the site.
