I grew up in Lake Shore, north of San Juan Ave. in a concrete block house built (according to the Property Appraiser) in 1950. A screened Florida Room was added at some point before we moved there in the early 1960s. My Dad had the screen 'walls' replaced with concrete block at some point - making it more comfortable, especially in the winter. Heat was provided by a kerosene stove at the bedroom end of the hallway.
Since St. Mathews Catholic Church and School (Grades 1-8) was close by, most of my friends went to school there. I walked to Hyde Park Elementary - about one mile, along 2-lane Cassat Avenue - no sidewalks and long before it became auto-dealer row (it was woods). I walked past those 'gateway' features to Lake Shore Junior High School. We were always curious as to why the school named Lake Shore was on Bayview Road, and the school named Bayview (Elementary) was on Lake Shore Boulevard.
That "town center" you featured had a locally-owned drug store with a soda fountain counter. Stopped there many afternoons walking home to get a cherry Coke - made with cherry syrup squirted into a fountain Coke. There was another local drug store at San Juan and Blanding, and another at Blanding and Shirley - this one had a great comic book selection, spent lots of allowance money there.
We'd walk to Roosevelt Mall before (and after) it was enclosed. At the corner of Blanding and Shirley, what is now a Gymnastics gym and a 'dog spa' was a Food Fair grocery, that became a Pantry Pride. The Dollar Tree was a Neisner's 'Five and Dime' store. My barber shop was one of the small storefronts between them.
We also spent a lot of time (and money) at the Classic Lanes on Cassat, bowling or (more often) playing the pinball machines (1 game 10 cents / 3 games for a quarter). I'm happy that it is still a bowling center.
I have good memories of growing up in Lake Shore.
