The Devils River is a short little river in far southwest Texas that empties into the Rio Grande.  It is largely spring fed, with piercing water quality that verge on Caribbean blues at times. I think more mountain lions than people live there.

I love it, and hope to get back sometime this year.

At dusk, everything slows to a calm.
