Books,
You mean they were actually shooting wild dogs in San Francisco in 1923? Yes, they were! I was chased by a few on my old Schwinn bicycle by the Great Highway as a kid.... Packs of dogs roaming the streets were a common problem due to the "dumps" being what it was back then....Within the city limits. I remember it clearly. There are Malls built over the old "Dumps" site...We would always call the theater built in that Mall years later as "The Dump". It's still there but it's sinking.
Once they moved the Dump, the wild dog issue also went away....but I think that was the cause back in the day.... The Great Highway (by the beach) was also a location of a small city dump that was close to "Playland" by the beach. You didn't want to be out alone walking the beach at night in that area! NOT without your bicycle gun!

I used to just carry a little kit of two Back Cat Firecrackers taped to a Kitchen Match, taped together, so when I struck the Match I had about two seconds before the "Bang! Bang!"...and this worked well to discourage the Dog Packs from worrying me as I rode my Bike.
I'd carry five or six of these in my Shirt Pocket.
This was in Tulsa, Oklahoma, 1964...
From there we soon moved to San Bruno California, and I became quite familiar with The Great Highway stretch, and mostly steered clear of Playland and the old Sutro Baths, that old Cave at Land's end, or whatever it was called...etc...Lol...
Late '60s, there were homeless people living inside of the fake Stucco "Rock Cliff" embankment there at the bend where Great Highway turned to become Geary Street...
Fun times! Lots of wacky stuff..!
There were still some old Horse drawn Street Cars in back Yards of the Sunset district then...no idea about now...
Moved the heck out of there in 1977...
Had I known about Bicycle Guns as a kid, I'd have sure wanted one!
