I had mentioned in a previous posting that it was necessary to start out early in the day if we were to see any wildlife. On Friday that was our intention, until we learned that a choir rehearsal for our park's vesper services was to be held that morning, and we wanted to attend that. So our plans went awry, and we left for Harlingen later than originally planned. There are two parks in Harlingen which are located along the Arroyo Colorado, which is a second branch of the Rio Grande River. It flows between the Rio Grande and the Gulf of Mexico. We were pleasantly surprised to find that the first park in which we hiked, the Hugh Ramsey Nature Park, had a lot of lush vegetation. It was a bit of a shock to our eyes to see such vibrant greens, when we have been seeing a lot of brown and grey plant life due to the lack of rain.
