Mostly write tickets.I kid!  I kid! In addition to doing their darndest to keep Texas' natural resources safe and flourishing, they also serve as peace officers within the state of Texas.  Taking Flight takes a look at the wildlife protection and law enforcement aspects of a warden's job, but in reality, the game wardens fulfill several roles. 

• Education
• Boating Safety
• Water rescue
• Hunter safety
• Disaster response
• State park maintenence
• Public safety
• Law enforcement

You can follow a real warden on a ride along on the Parks and Wildlife podcast. And of course, there's even a podcast episode about bat colonies.  

Some game wardens are apparently great kissers, though. I don't know from personal experience but I'm going to go out on a limb and say some of them probably are.
