I used to do something like that...

Make a bunch of drinks.

Grab a bunch of $1 shot bottles.

Throw em in a cooler with ice.

Head out to the park on hot days.

$3/drink

$2 if you wanna make it an adult drink.

I may have to do a version of this for winter with Baileys and hot coco...🤔

Do kids now a days even play at parks during the winter?
