Yes I was there on the Sunday and what a day that was,most of the points have been mentioned above but I feel that I must say my piece as well if only to clear my conscience.
Before I start I'd just like to say that the Air-Racing was brillant and was run in a very professional manner as always(No I don't race).
The shear lack of airfield understanding & discipline that I witnessed within those few hours is hard to describe,how any airfield operator can expect to 'get away' with such laxed measures is beyond belief:-
Several A/C were cleared to land at there discretion whilst at one point 6 rally cars were on the runway (26),it also became common throughout the day for cars just to cross the active runway with no help from a radio or marshaller.
The A/G Radio service was almost non existant with A/C calling for radio checks until another A/C would come on frequency and answer them.
It appeared that the rally cars took priority over the A/C as at one point an A/C on a 1/2 mile final was asked if he could land over the backtracking rally cars! When he declined he was told to orbit present position !

I would have liked to have had a look at the amount of FOD being dropped on the runway off the cars,especially considering that as part of the rally circuit they went on & off fields with sheep grazing in them,thats a really responsible attitude to the F&M outbreak is'nt it !

A friend of mine waited 25 minutes for fuel whilst the two 'multiskilled' dozy idiots in the fire truck drove aimlessly around the airfield playing a cross between Fireman Sam & Colin McRae.
On a serious note I only hope that the standards improve quickly before someone is seriously injured,especially with the summer coming up as on a good day Caernarfon can see 100+ visiting A/C
One final point,does anybody know what happened to the Pup with a missing propellor,I presumed that it had dropped in a Rabbit hole as there was a 8" deep cut taken out of the grass nearby.
