The Ladies Of Hydrology atop Enchanted Rock.

Geary Schindel of the Edwards Aquifer Authority gave us a day-long field tour of the recharge zone.

Here he shows us a cave entrance in a creek bed which allows a huge amount of water to enter the aquifer.

This is an old industrial well which is now used for monitoring the aquifer.

Dave gets a first-hand sampling of the smelly water from a well in the "bad water zone."

You can't visit San Antonio without seeing The Alamo. Inside, men are required to doff their caps to make sure you respect the shrine of Texas's honor.

Our final dinner in San Antonio was a Tex-Mex extravaganza!
