I think money is short for everyone, public funding or not, and we all need to make sure we support our museums in any way we can.
Different museums have different strategies and constraints on fund raising, but at the end of the day if people don't support the museums in one form or another they may not be around for future generations.
Shows are one way of supporting any museum, and this weekend I urge anyone reading to consider attending or displaying, whether it's at Duxford (Military Vehicle Show), Shuttleworth (D-Day Air Display), Debach (Airfield Open Day), or any other museum. We all need all of the help we can get.
