We have owned this house for 21 years.
This is the first time something like this has happened.
Sewers set out, and ... eeewwww.
This is what the basement looks like (the rest of the rooms are more of the same) :
Fortunately, only one essential trunk (with photos and family papers) was hit by the water, so this is what the living-room and the kitchen looks like (and the rest of the rooms are more of the same) :
I think, possibly, that this will be the event that finally pushes me to scan the family photos, my parents' love-letters, and other family papers, and begin processing them.
It will be a few days before I'm back with you.
