Last flight of 2023. I did air work with slow flight, stalls and steep turns - intercepted my wake multiple times :) Got “cheap” fuel at KSNS where the tower closed between 9:45 and 10:30 and ATIS instructed traffic to use tower frequency as CTAF. I guess single controller operations… The video below is of a tight pattern, hard slip from 300ft, wheel landing and exit by taxiway closest to the fuel pumps :) https://rumble.com/v42um3q-c140-no-twr-ksns-for-fuel.html
