Every year, hopeful cardboard artists put their hard work into themed vehicles likely to fly apart or dump their cargo before reaching the bottom of the tubing hill at Roundtop Mountain Resort.

The crazy contraptions hitting the slopes at this year’s Cardboard Derby will feature a 50 Years in the Future theme. Catch the chaos at 4 p.m. Sunday, Jan. 29, at the resort, 925 Roundtop Road, Warrington Township.

Admission is free for spectators.
