To stretch my leg we take tiny breaks, here and there - often parked in some ranchers drive way or a small dirt road that gets little traffic. We see lots of things. This trip we saw a pair of Mexican eagles wheeling in the sky, deer feeding in some of the rocky fields and construction to widen a road. We also found some antelope horn milkweed or Asclepias aserula . You can read about it here... http://www.wildflower.org/plants/result.php?id_plant=ASAS It's also called spider milkweed but I prefer the name Antelope Horn
Texas has an amazing assortment of milkweeds and other wildflowers. Our bluebonnets are doing okay this year despite the shortage of rain and cool weather.
