Yeah, even if I had the SW 16mm prints (which I don't) there is no way I would send them in the mail.
I had some home 8mm films of my Mom, Dad, Sister and I transfered to miniDV about 15 years ago. But when I did I drove them to the facility. Dallas/FW area for us both. Not close to me, but worth the drive to know where I would be able to pick up the original films again - priceless.
