There is a local Houston security conference that occurs every year or so called HOU.SEC.CON. The next HOU.SEC.CON will be March 23, 2017.
I have been wanting to make it for a few years but it seems like I always have a conflict. This year, however, I will be able to make it and I am looking forward to it.
If you are interested in infosec and will be in the area, you should check it out.
