Welcome to the Swamp!
I remember well how it felt to have all that shining new gear and no firm plans to put it to use. I, too, certified in the fall, near what most folks call the end of 'dive season'. (Timeliner, you don't fall in this group...as do some others and you know who ya'll are!)
Hope you can find some dives soon. However, since you're looking at dives close to DFW, I'm guessing that you a)purchased a 7 mm suit or b)got a dry suit (but I sorta think not) or c)you have a huge tolerance for cold water. I'll be making a trip in January (no December weekends open), but even that will be to Balmorhea. Seventy degrees is about my cutoff for surface temps.
Have a great time and I hope you get some dives in soon. Again, welcome!
