I thoroughly enjoyed the event on Saturday too.
For me, Sywell is my local aerodrome when I'm in the UK. IMO it's a crying shame it's not always as friendly as it was on Saturday to us non-flyer-inerers.
All locks, gates and access codes isn't the best way to encourage more GA activity. It reminds me way too much of Australia - maybe my ASIC will help me through next time I visit on a non-PFA day.
