Sister Rietz, as you know, was transferred a few weeks ago. I have been waiting for her new address, and just found out that all letters and packages should be sent to the mission home and will then be forwarded on to her in Upland. If you send packages USPS, it is much easier for them to be forwarded than another provider.
Thanks, Amber's Mama
