Our next stop was in Spearfish, South Dakota, one and a half hours after leaving Buffalo. I was beginning to feel the effects of flying at 13,000 feet that morning, without oxygen. I felt tired, but was still alert and fully capable of focusing on my flying, so it was nice to have a break often. We flew on to Pierre, South Dakota, where we had reservations to spend the night at King’s Inn. The motel owner, who was very “pilot friendly” came and picked us up at the airport and then took us back the next morning. They were very accomodating. We learned from the natives that the name of their city is “peer”, not “pee air”.
