What is Cardboarding?
1.
The summer and spring version of winter sledding (on snow). Cardboarding takes place on a grassy, steep hill and instead of riding a plastic or metal sled, you ride a large piece of cardboard.
It may sound hella lame, but its actually quite amusing on a summer day.
"I miss sledding :("
"well we can go cardboarding now that summer is here!"
