Nice.
The best I've seen was 24MB down/8.7MB up, going across the causeway in Galveston,. But I haven't repeated anything close to that since. That time I carried 4G all the way into Hitchcock and lost it it maybe halfway through.
Sitting in my office in the medical center, next to a large window, I've lost connection several times and got 1.3MB down and 809K up. And that's with full bars.
Still better than at my house though, since I roam there!
