Rustlers' Valley

There's an exciting opening sequence where Lucky is chased by a posse & jumps off a steep cliff with his horse into a river. The heroine ("Agnes," played by Muriel Evans) looks like a cross between Claudette Colbert & Loretta Young (I guess this was a popular look in 1937), but isn't as pretty as either. Agnes & Hoppy have a conversation about his horse (oddly, Hoppy says "I don't know much about his past"), whose name is not mentioned (& later, "I shouldn't have let you ride that white horse"). Which makes me wonder, what was the first time Topper was called by name? I'll bet that other horse owners would be able to say more about their horses, like Tarzan, Duke, Trigger, Buttercup, Champion, etc. Often in Hoppy films, the name of the town is made known, but not in this case, & that's a shame also, because this film's set in one of the more unusual western towns, a town with a tree lined dirt main street, where there are no hitching posts, but the horses are tied to metal rings set in the trees. Question for old west historians: is this detail realistic or complete fantasy? A good film & mildly interesting, but a little slow. I rate it 6/10.
