>Many of us take air travel and transportation in general for granted. We are a bit sensitive about this topic at present. I never cease to be amazed at how people in North America around the 1840’s as an example, traveled vast distances. Not everyone of course, but it was done by a number of persons who either wrote books or books were written about them.

I thought about this many times on my drive home from San Diego. When I crossed the desert, I thought man what was it like back in the 1800's when someone wanted to get across this. Getting maybe 20 miles perday was good.
