Cardboard box derby at Grand Targhee
Grand Targhee Ski and Summer Resort began to wind down the 2017-18 ski season with its 18th annual Cardboard Box Derby Saturday.
The competition requires teams to build and ride snow crafts made out of cardboard, paper, glue, tape and string. One of the few rules requires a team to be able to stop their craft, then clean it up and take it home.
