Hoppy, Windy and Johnny get the herd through to the starving townsfolk despite the best efforts of the bad guys to thwart them! Based on a Mulford novel, this one has a more interesting and solid plot than most series entries. The photography is awesome and the trail drive convincing.
Gabby (Windy) gets a chunkier role than usual - he even gets shot - James Ellison displays the requisite amount of charm as he woos Gwynne Shipman and Hoppy was never more authoritative. The sinister Morris Ankrum is just one of a formidable array of baddies - how could he be anything else? - and there are a couple of good songs, apparently sung by Ellison although I stand to be corrected.
This is high quality entertainment, possibly the best of the 66.
