Mailing list errors

I've maintained various mailing lists for over 25 years, so I know how hard it is to keep current. We updated the list as best we could, but still got "Not Deliverable a Addressed - Unable to Forward" notices from the Post Office for those below. So if you talk to them, tell them we tried but the address we had did not work.

I find it particularly frustrating when the Post Office says it is unable to forward then gives me the correct address!

Letters returned addressed to:

Rilla Forest
George Hudson
Liz & Garret Jakobsson
Amanda and Mark Kishell
Ashley and Travis Phipps
Ruth Roeder (and they told me where to send it to!)
Blake and Bobbi Stockton
