SCORE Baja 1000 Experience at SEMA was showing a very interesting documentary, about the many problems and challenges in the race (anyone know exactly what the video is named or who made it?) and I hadn't heard of the boobytraps created by locals so they could watch crashes happen

 

the video in the Baja area in the North Hall showed several boobytraps, but I can't find examples on you tube 

here's a bad one https://www.pinkbike.com/video/92140/
