I just talked to the Chief Ranger of the City Parks, which includes Lone Star. He said if you don't find anyone at the shack at the gate you can do one of two things. Sign in on the daily log there at the gate and go ahead and go fishing. You can pay the first ranger you see and if you don't see one just pay the next time you go or there is usually always someone at the equipment shed/office at the back of the park where I explained earlier in the thread. Just call the number I posted earlier and someone will meet you at the gate.
