Bradley is on the mend following his rodeo injury and determined to get back behind the wheel of the RV. As the pair continue on their journey, Barney is thrilled to be celebrating his birthday with a trip to the iconic Niagara Falls. Later, Bradley and Barney take the RV on a small cargo ferry as they head to Vermont. Here, the pair have a go at ice climbing, which proves treacherous for them and the crew, before a spot of dog sledding through the frozen wilderness and an inevitable race through the forests.
