Never fear, for the Militant is here!
As long as the temps stay high, the Militant will run special posts on how and where to STAY COOL! He's done something similar, like his Pulitzer-Prize Winning** series on Ethnic Iced Desserts, which are still very much valid today.
The Militant doesn't like to reveal very much about himself, but he will let you know this little fact: He was a Foster child.

Childhood Operative: Remember the Foster's Freeze down the corner?
Militant Angeleno: Aw hell yeah! The Militant never forgets!
C.O.: Remember the day a car crashed into the side?
M.A.: Heheh...yeah...
(The driver, coincidentally a family friend of the Childhood Operative, was okay, btw...)
Sometime in the early 1980s, the old Foster's Freeze in the unspecified neighborhood where the Militant grew up in was bulldozed, and replaced with an ubiquitous local icon of retail banality. Sigh. Paved paradise, and put up a mini-mall.
Today, while passing along Fletcher Avenue in the AWV (that's "Atwater Village," in Militant Code) he saw a familiar-looking blue building with a neon sign with the smiling ice cream mascot. The Militant felt like he was 9 again.
Mommy? Mommy? Where are you, mommy?
Oh, wait (looks around), uh, heheh. Never mind that.
Okay, so they cost $1.80 now, as opposed to about 1/7th the price back then...
Regardless, he was a happy "Lil' Mil" again, sinking his teeth into the thin chocolate shell, revealing the soft, cool, vanilla soft-serve goodness inside.
Bliss.
According to the company's website, there are still 101 Foster's Freeze locations still in operation across the Golden State, including the very first location on La Brea Avenue in Inglewood, still in operation since Mr. George Foster opened it in 1946. And no, those joint-venture Foster's dispensers installed inside nearly every El Pollo Loco do not count.
But still, for the Militant, and many other Angelenos who grew up within walking distance to one, a Foster's Freeze is now a rare icon of the past, unabashedly displaying its postwar-era, Route 66-ish image. When the Militant passes by one, and the temperature is right, he will stop by.
