Narrative:

It was the last leg of a 4 day cross country from coast to coast. My friend was flying the plane and he made the landing at ZZZ. The touchdown was on the centerline of the runway. Winds were 20 degrees off the nose at 10 KTS gusting 20 KTS. We didn't correct for the crosswind during the rollout and lost control of the plane. The right wing came up and the left started to drag on the runway. I took control as we were departing the runway and hit a taxi sign with the right horizontal stabilizer. We were able to taxi in to parking. I think we were both very tired; as it was almost 25 hours of flying to get the plane across the country. I know for me; I was happy to be on the ground and done with the flight; and just when I needed to be most cautious; I let my guard down. My friend has approximately 150 hours of flying and about 30 hours in tailwheel aircraft.
