Well Isa if I am to consider a regular person I do have such an over because I have a garden.
According to the article though, this is a community oven.
In my village , Kardamyli of Mani although it was not a very poor village because of the olive oil trade, we had three community ovens.
Three... Three main rivarly families, three vendettas, three ovens...
As grandpa was saying, the Three Evils of our Destiny.
Those community ovens were run by three elder widows of the village. Usually poor. The payment for using the oven was a loaf of bread to the woman that was in charge for baking.Obe loaf drom every " client".
The oven was on duty three days a week. During those three days she warmed up the oven three times...
After the dawn the baker was climbing on her veranda ( our houses there are like fortresses, tall with no windows, just a veranda with holes on it's floor in order to fight the " enemies" . We spill hot oil on their head

)
and was announcing the first "baking session"
My grandfather was insisting that the second baking session was making the best bread. Don't ask me why! I don't know
The community ovens as those that are discribed in the article are kind of arks of civilization for a place.
I hope that the experiment in Canada succeeds.
