My best advice for fishing around "the city" is to just find any ponds/drainage ditches/etc. with water. 99% of the time, they will have bass of some size- if you're lucky they could be hogs. I'm in Richardson, which is just above Dallas. If you want sandbass, crappie, etc. there are several big lakes above Dallas that provide good fishing as well.
Also put some time into your spots. For example, I don't have a car- so I take the bus to a nearby neighborhood pond that sees a LOT of pressure, there's almost always someone fishing and on the weekends there can be groups of 10 around this pond. However, to fight the pressure I started going at night, twice a week, almost every week, trying every tactic under the sun, and simply sticking with what works- I have landed bass up to 5-6 lbs from this neighborhood pond as a result, where others have completely skunked out.
Good luck, and welcome to TX
