We had a small group consisting of Bruce, Terry and myself, and spent 5 nights in the Big Bend area in April, 2016. We were reminded during our visit that arid, very dry conditions are the norm for the area. A few plants were blooming, but nothing to compare to spring 2015.
Three of the nights were clear enough for Milky Way photos, plus we were able to get some interesting early morning sunrise shots. I took my mountain bike and rode the Lajitas Airport Trails network searching (in vain) for wildflowers. But, I was able to find a few plants blooming.

I used my new Nikon D810 camera and Nikor 14-24 mm and 24-120 mm lenses for all but one of these shots. In addition to the benefits of a very large full-frame sensor, the camera has fantastic low-light capabilities compared to my previous Nikon D300S.
