It is a peaceful and beautiful stroll along trails overlooking the Hidalgo Canal.  Huge steam driven irrigation pumps are silent now and the rustic brick structure of the pumphouse provides a popular backdrop for photography of the native plant gardens.  A green striped border control vehicle rolls by.  No surprise, we are just ½ mile from the Rio Grande.  We relax watching the Kingfishers.  Another green stripe goes by then a flock of Parakeets.  Stroll the dike, another rolls by.  Hmm, even busier than we expected.  Down by the canal one of the border police guys is out of the car.  A green pickup carrying more uniforms.  Radios squawking and more striped cars both sides of the canal.  Our stroll is briefly interrupted by “There are new immigrants down there.  Be careful.”  Officers exit cars and we divert our walk just a block further into town.  The sounds of barking dogs, a helicopter overhead, and loud voices in English and Spanish reach our ears.  Just another day in border Texas I guess.  The canal-side encounter didn’t even make the local news.
