Topic: Trying to Find a Rental in Northern California

Hi, I am at my wits end.  I went and got a CITES permit for my bassoon so I can go on tour with my youth orchestra (my bassoon has an ivory ring as it was inherited), only to find out that there are all sorts of additional steps I need to go through in order to actually travel with it.  So instead, I am looking to rent one and needless to say, they are impossible to find.  Any suggestions other than having the ivory ring removed, which I would rather not do?
