Great story, great park

Thu, Dec 01, 2016

I was pleasantly surprised when I read the story on Big Bend National Park (fall 2016). When I began reading I thought I was reading National Geographic. The feature was extremely well written with quality photography. The park, indeed, offers great photographic experiences that are quite different in the fall and the spring. It is one of the best places to view the galaxies and stars of the Northern Hemisphere due to virtually no light pollution. Best of all, the park is not nearly as crowded as some of our other great parks.

Hopefully, some readers will be inspired to visit. If you do, be aware that there is very little dining in the park. For a very unusual experience, visit the fascinating ghost town a short distance from the west entrance to the park called Terlingua. There you can have wonderful dining experiences as well as some nice surprises.
