Interesting concept!! I take it that this is some terraformed moon of Jupiter (or a habitable moon orbiting a Jovian-type planet somewhere else in the galaxy), and the humans are using space yaks to get around on the chilly, icy moon. Very nice concept. I like it a lot, especially all the details you put in- the furry creatures, the spaceship, the packed saddlebags, the space gun shoved in the saddle holster, the dog's packs. I also like the sense of being up in the mountains, and the gas giant looming over the horizon. I wanna go on the TransEuropaExpress...
