I used to get my night currency at KPHX (after the commercial guys had gone
to bed) without flying patterns. Tower would have me takeoff, turn a 180 at
the end of the runway, land, stop, then throttle up and do it again in the
opposite direction. Three full-stops took about 5 min.

I've done the same. It's fun! G
