Recalling the satellites…

In the 1850’s people crossed the country in covered wagons. They died of dysentery and cholera. The trip took half a year and if they didn’t make it before winter, they could get stuck in the mountains and have to eat their friends and family just to try making it through to spring. I’ve always been amazed at people’s capacity to make this trip, but recently another thought occurred to me… How the hell did they manage to tolerate the trip without satellite radio or an integrated GPS? I can’t get halfway across town without either one of them.
