This may be a bit of a long shot, but we have a large loan return that needs to get to the CalAcad in the coming months.
As it is nearly 7000 specimens, we figure it may be worth seeing if anyone is driving from the Michigan area (within a ~4hr drive) to the San Francisco area some time in the near future and has room for about 10 drawers. It would be helpful to avoid mailing this many delicate specimens, so if you would be willing to help out, please let us know and we can negotiate the details accordingly.
Thanks so much for your help and please feel free to contact me if you have any questions.
