Today is the Bio-blitz at the Rio Grande Nature Center.   A bird walk has started,  and a porcupine walk as well.   It is a nice,  cool day here.  Roadrunners dart across the ground.  A turtle was brought in from the Bosque for viewing.   He is trying to climb out of the cooler.   Binoculars can be checked out to take on the nature-viewing walks.  Speakers and experts come in to present on various topics related to nature.   All of this for a $3 parking pass!
