20 photos show how summer vacation in the US has changed over the last 100 years

• Summer has officially begun.
• Summer vacation these days looks quite different from how it did in the 1920s.
• Kids used to play sports in the streets, explore on bikes, or play on “dangerous” playgrounds. 

Kids didn’t need any fancy technology; a stick and a hoop used to be more than enough to keep everyone entertained.

Stickball was the sport of choice, especially when there was no grass to be found.

Sometimes, all you needed for a fun time was a tarp, soap, and a hose — voila! A makeshift slip-and-slide.

Sports are well-organized these days and significantly less dangerous.
