It depends on the item. If I arrive at the cabin myself, and find something,
I call - hoping they are still in the area and can come back and get it.
My cleaner does not mail anything. I let the guest know what has been
found and ask if they want me to send it to them (some things can not be
mailed). When I have the item in my hands - from the cabin - I mail to them
if they give me their mailing address - and they reimburse me for postage.
Some do not want it - item is trashed - or donated to the local to Salvation Army.
We do not have space to store things.
