BigBendHiker, great photos!
Government Canyon is such a jewel for San Antonio.
One can have a nice 1 hour stroll on flat ground, or a 15 mile hike over fairly challenging terrain (and never cover the same trail twice).
While I have not been there in a couple of months, for the longest time I was there just about every weekend to work up a good sweat and clear out my head. And it is less than 1/2 hour from downtown San Antonio.
Last Spring, the flowers were out of this world, and seemed to last way past May.
Even without the flowers, its a place you have to check out!
