We've passed dozens of pecan orchards like this one, sometimes getting a whiff of a pecan or two as we wizz by.  One of the beauties of cycling is that you not only see things up close, but often smell them as well.  This does not always translate to pleasurable things, but I've discovered that alfalfa is a treat to sniff on the road, and the orange blossoms in California were pure heaven.  These orchards are irrigated and look flooded for awhile before the water settles into the roots.  We've been passing countless irrigation systems since the trip began.  Recently the cotton crop has been planted in NM and the part of Texas we're now in.  I won't say this out loud but we have yet to see a drop of rain, so it's easy to see why irrigation is needed for everything in this climate.
