December 14, 2002.  The VLA is a group of telescopes on the San Augustin plateau.  Each telescope is a big dish receiving radio waves.  They are spread over three lengths of rail track, each track leading from a central point, like a giant "Y".
Approaching the VLA.
The welcome sign.
To the Tour.
A dish.
The same dish, after rotating about 90 degrees.  Just after I took the previous picture, all the dishes began slowly turning in unison, searching some other area of the sky.
More dishes.
