Rex & Yukon King were a big part of the series. Dick Simmons looked every bit the Mountie and could sit Rex well on his English saddle. He was even better with sled & team of huskies with King in the lead of course. This was one of the few 50s shows shot in color but shown in B & W.
Big Bear Lake Ca was as close as Hollywood could approximate for the Yukon in the 50s. So sit back relax and enjoy "...in the wild days of the Yukon. Back to the days of the Gold Rush, as Sergeant Preston, with his wonder dog, Yukon King, meets the challenge of the Yukon."
...."On King, on you huskies!!!!"
