Well I'm spoiled for choice, I can either:
Go down to the NVR and enjoy myself down there and plus get brush up on my guard knowledge - free travel

Go up to York, try and get a decent photo or two of the A4s (knowing how busy it will be) - free travel
If I wasn't working Saturday, I would have gone to York on Saturday and the NVR on Sunday...
Anyway, I'm a big fan of the Poles so should be able to go down there and enjoy myself...
