Fascinating!
Still it doesn’t mean others didn’t make one in their backyard or other private area.
Obviously we aren’t necessarily talking about homogenous 10 foot outdoor fires in the middle of the street with hundreds of participants…
It probably depended on the city/neighborhood/neighbors, but a modest fire in a private area might totally have been possible.
(The 1956 number for Stolin does make more sense than @Motcha’s 1910…..)
