You dont mind dealing with unacclimated people who do not know how to drive on ice/snow. Granted, the roads are not bad *yet* but the "Im a Texan, I drive a truck" idiots who refuse to slow down are out in full force today. Plus, one of the major Fort Worth/Dallas highways is closed for major construction, creating another mess. Try back in about a month or so, then the gods of thunder will be here to show you a real sight.
I lived up north for 14 years. People here in Texas cannot seem seem to get adapted to any kind of snow or freezing rain. If you value your vehicle, stay away. If your already here, find a place to hide! Traffic is terrible during this time.
If you are in the Stockyards area in the evenings, and the nightlife is usually booming. When closing time is near, many of the local cowboys tend to engage in fighting and the surrounding northside area is not the safest place to be walking at night.
When an ice storm hits, its best to stay at home. I was always lucky and never had an accident thanks to my learning to drive in the middle of winter in Massachusetts!
Please don't try to fish the Koi with the poles you see around the Japanese Gardens... they are for drowning purposes only :-)))
When the Fort Worth Herd is trailing up through the Stockyards, make sure you stay on the curb otherwise you will have this lady to deal with. She will quickly direct you back to the pavement.
Just like any place Fort Worth has crime but if you stick with the nicer areas you will be alright. Watch out for Tornadoes this is part of Tornado Alley.
