I should walk if I am just dropping my car off at the car wash?
(I got a more thorough puzzling answer than I saw online. Claude nailed it, though.)
Why did the two kids on the left change their shirts?

Hi Duane.
I think these should all of these have the sign up as tinyurl.com/CMCSymposium26 and not tinurl?

Marram grass leaf. Light micrograph of a cross section through a closed (unravelled) leaf of Marram grass, Ammophila arenaria. The deeply grooved leaf is thrown into folds. The folds conserve water and withstand salt, and prevent excessive evaporation. Round vascular bundles are visible inside each fold, serving to transport food and water through the leaf. They look like smiley faces. The large "eyes" are the xylem, which transport water. The bright blue "mouths" are the phloem, which transport sugars produced during photosynthesis. The spiky, curved structure is a natural adaptation to drought conditions, helping the leaf to roll up and conserve water. Spines on the surface discourage animals from eating the leaf. Marram grass is important in coastal ecology, since it is one of the commonest grass species in Britain to stabilize sand dunes.
Mother nature is a raver.

Black-and-white portrait of Virginia Holsinger (1931–2012), the pioneering American food scientist and inventor who developed lactose-free milk. She is shown smiling warmly at the camera, with short, light-colored wavy hair styled neatly. She wears a dark blazer over a dark top, accessorized with a long beaded necklace and a patterned pocket square tucked into the breast pocket. Small dangling earrings are visible, and the blurred dark background with foliage suggests an outdoor or garden setting. The image conveys approachability, confidence, and accomplishment.
Color photograph of a grocery store dairy shelf displaying various cartons of Lactaid brand lactose-free milk. Prominently featured are half-gallon cartons in different varieties: 1% Lowfat Milk (light blue), Calcium Enriched Fat Free Milk (purple), Protein 2% Reduced Fat Milk (dark blue), 2% Reduced Fat Milk (blue), and Whole Milk (red). Each carton features an illustration of a glass of milk splashing next to chocolate chip cookies, with the Lactaid logo and "100% Lactose Free" labeling. Price tags show $2.57 each with "Buy 2 Get 1 Free" promotions, highlighting the product's availability for lactose-intolerant consumers.
On National Milk Day, let's celebrate chemist & food scientist Virginia Holsinger, whose enzyme research revolutionized dairy for millions. #WomenInSTEM
Her work laid the foundation for Lactaid® products, making milk digestible for the lactose-intolerant & improving nutrition worldwide. (1/2)

"It is a bigger difference between 0 and 1 than between 4 and 5." - Tadej Pogacar
This is not a math problem. Bike races are hard to win.
Tadej has won the Tour de France four times, but he has not won Paris Roubaix. The first one is the hardest.

Black-and-white photo of Dorothy Vaughan in front of an IBM machine (computer maybe?). She is smiling, her hair is up, and she is wearing a sleeveless dress with a multistrand of pearls.

Python: The Documentary. A fascinating watch, I think even for non-coders (or the code-curious). Watched this last night and both enjoyed it and learned some new context to my programming!
