This is a very safe way to start your kids in offroading. It is a '01 Yerf-Dog offroad kart set up for sand. Has a headlight and tail light. Yerf-Dog claims it can seat two full size adults. That's a stretch unless they are pretty small, but a full size adult and a child is realistic. It has a 9hp Techumseh power sport motor mated to a Comet 30 series Torque converter. $1200 obo. Trades will be considered.

EDIT: Changed sentence to say 01'.
