Departed GPM at 2500 with a southerly heading until clear of Cedar Hill (all the big towers). Once clear; I started to turn left to overfly JWY and climb to 3000. After Class B; I started my climb to 7500 toward the Little Rock area. I was using Terrell (TRL) as a fix and a check for weather (altimeter) when I noticed something that looked like a bird. Since I fly a lot in the SGT area; I see a lot of birds of different types - and I thought I was seeing a bird at first. I thought - good; I'm higher and the bird should not be a factor. Then I tried to re-focus my eyes as the movement wasn't quite like a bird - close; but not the same. Worse; my brain was not making sense of what kind of bird this might be as I was trying to 'see' a black vulture. What my eyes kept telling me is this black vulture had four evenly space red dots (as a square) on its back!Then I got mad - that's a drone. And since I don't know a lot about them; I have no way to process how close the drone was. My best guess is within 500 ft.My position: about 6 miles southwest of TRL at 7500 flying a magnetic heading of 065.
BE35 pilot reported a NMAC with a UAV at 7500 ft in the vicinity of TRL airport.
