Having spent a disproportionate amount of my life hanging out at grass airports (or grass being used for takeoff and landing whether or not it was designated as a runway) it's interesting to watch the differences in pilot behavior and technique.
The most-disturbing tendencies are the efforts to make things happen before the airplane is ready, during both takeoffs and landings. "Pulling green" before the airplane is ready to fly and then mushing along nose-high in ground effect is quite common at Gastons, Cedar Mills and numerous other spots where my chair is often parked under the wing.
As DK Royal said about throwing the football, "when they do that, three things can happen; two of them are bad."
