i think it's more likely what kind of road kill covered wagons made for the wild west. u always see pics of a wheel off over here and the wagon over there, and bonnets hanging in the breeze. do u realize these people had to overcome many many fears. the fear of coyotes and wolves, bears, buffalo when they were migrating, indians (some not all) and visa-versa, and, then, what kind of weather they would have or not have. for instance, just circling wagons didn't mean that a severe thunderstorm wouldn't leave them all in a big pile of mud. i can't imagine the sweat and toil and blood it took to migrate to west. of course, in russia, u have migrations in all directions, too. across the bering strait and into alaska and along the rivers. when russia left alaska - many orthodox churches were left. (just as with missions by the spanish in california). it's really itneresting to see these places and the lives people led hunting, fishing, trapping, etc. a much different life than those who stayed behind - and yet, for all the risk - it was an adventurous life.
