Narrative:

On a day; VFR flight to oshkosh for the annual eaa airshow; I was traveling with another pilot. I was flying and asked him to navigate. We were using GPS to fly directly to our intended waypoint; ripon; which is the start of the VFR arrival procedure into oshkosh during the eaa show. He was monitoring our progress on a current chicago sectional chart. I asked him to keep me apprised of any controlled airspace. As we were flying I happened to see that we were close (about 3-4 miles) to a large runway. It turned out to be ues; waukesha; wi. I turned the plane abruptly; directly away from the airport; but estimate that we penetrated the class D airspace without contacting the tower by about one half to one mile. Although the other pilot is an experienced private pilot who has made the trip to oshkosh by himself or with me or others at least a dozen times; I should probably not have relied on anyone else to navigate and should have kept the chart myself.
