I was on call, so I got up and cleared out the overnight stuff, then headed to the airport to cook breakfast for the LRAA display day. When everything was put away, I went over to the hangar and got the plane out, then flew down to Columbia to meet Chris and Steve (passenger) for lunch - there was a fly-in there that we'd been invited to by Kim and Victoria, a couple we met up at Auburn a few months ago. They had a temporary tower there (interestingly there was no NOTAM that I could find), and they told me to call overhead at 2000'. The runway's at 2100', so I assumed they meant 4100', so called that when I was above. The controller told me to fly North and to expect a right downwind join for 17. When I was about 2.5 miles North, he said I could head for downwind, but that seemed odd as I was upwind of the airport, so I suggested I just do a straight in approach, rather than tie up the runway for that long (they'd been racing cars up and down the runway when I flew overhead). I got him to agree, so I just turned in and flew to the threshold - he wanted me to take the first turn off to the right, on the grass, and I could see that a fair way down the runway, so I flew low until near the turn off, with the controller getting more upset that I hadn't landed - I landed and stopped right by the turn off, then followed the marshall to park just 2 spots up from Chris. I got out and sorted everything out, and Chris and Steve arrived having watched me land. We wandered about a bit looking at the stalls, then ordered a pizza and went to see Kim and Victoria at their hangar while we ate. Chris had to get home for his wife's birthday, so we headed out just after 14:00. We had to wait for the car races to finish, then crossed the runway to the taxiway, then had to wait for the car races again before we took off, pretty close together. The controller asked us to do a low pass, so we came back around and did that before heading North West towards home - they dropped off towards Cameron Park, and I headed back to Lincoln - it seemed to have been a long day, but it was less than 3 hours flying.
