While performing a touch-and-go landing on a turf runway, the newly tailwheel-endorsed pilot encountered a sudden crosswind. The airplanes nose turned left as the airplane bounced back into the air. The pilot initiated a go-around and added right rudder. The airplane then exited the runway and headed for an airfield wind indicator, so the pilot reduced engine power and maneuvered the airplane away from the obstruction. The airplane settled into a plowed field, nosed over and came to rest inverted. The pilot was able to egress the airplane without assistance. The airplanes firewall, both wings and both struts sustained damage.
