How do I automatically bind mount on boot in a non-root encrypted home directory?

I want to bind mount a directory within my home when I log on. The line in fstab would be

/foo/bar /home/me/wherever none bind 0 0

The trouble is my home directory is encrypted, so it has to happen after I log in. The problem is my login scripts don't have permission to run mount.

Is there a way to do this?
