Typical government bureaucracy at work once again.
Spend taxpayers money at will instead of getting freebees from the same.
I can imagine the costs of transporting to and from museums plus the added costs of personnel, per diems and accommodations rather than the basically free cost of utilizing civilian volunteers and their vehicles...
In reality, most MV guys seldom ask for much, often fetting the bill out of pocket themselves for the pure enjoyment of proudly displaying their vehicle.
It makes sense to me more and more why many MV guys stick to themselves or stay below the radar rather than interact with formal groups or government institutions.
Furthermore, the boys down south (USA) seems to be able to handle these situations in a whole different manner to the benefit of the Public (taxpayer) at large and encourage participation from the Civilian populace without a lot of political nonsense and insurance obligations. Perhaps their way is a whole lot different than the way it is here. Sad.
