Ever had an ongoing contest moved to another site?

Within my club there is some controversary surrounding the question of
whether or not there might exist precedent for moving an ongoing
contest to an airport other than the airport that had been originally
intended. Whereas it is not resonable to take the entirity of our
little club issue to this world audience, it would be most helpful if
anyone aware of such a happening could cite the occasion. Most
particularly, the case where a competition director might have decided
to move a contest to another airport due to some aspect of weather
forecast or occurrance would be of greatest interest. The question
relates to club contests or sanctioned contests. Thanks in advance!
