Someone from the UK would appreciate having it in the UK not on the East Coast of the US.
I don't see why, given the relatively small size of the UK that some central place near a large city e.g. Manchester/Birmingham/London/Cardiff/Newcastle/Glasgow, that was already holding a folk festival, couldn't act a get together point for UK MudCatters.
I've been to places in Scotland ( Newcastleton ) and the North of England (Rothbury) where the whole town is given over to music for a few days so being able to play wouldn't be a problem - same is true on West Coast of Ireland during festivals.
In Newcastle there's the annual Fish Festival festival at North Shields/TyneMouth
Didn't someone say in an old thread on the same subject that they had a URL for all the UK festivals ?
