All normal until tailwheel lifts off and plane wind-vanes violently into gust.  Force tail wheel back down to regain control and a second later the plane lifts off and does a pretty good imitation of a butterfly caught in the draft of a semi.  Soon in control again but combination of low airspeed, P factor and cross wind has plane pointed 45 degrees away from course down runway.     And of course,  all in front of an audience of die-hard rotor-heads who were still at Bill's place.  Sigh....   Tracy (adding glasses to preflight checklist)
