Aurora is a trickier question than most places in CO. The problem arrises from the city straddling the Denver county line; Aurora itself is entirely within Adams, Arapahoe, and Douglas counties, but it's pretty tricky to tell where one county ends and another begins with the continuum of development. Since Denver has a special ability to regulate open carry, you've got to be careful that you don't cross over. Inside Aurora proper, since it's not in Denver, OC is legal everywhere that it's not specifically posted to be disallowed. Aurora actually bothered to ammend its municipal code after preemption was passed to reflect this, and I'll paste it below in case you want to print it out and carry it with you.
All that having been said, I have myself OC'ed in Aurora a few times and not had a problem. People may be more jittery about it so close to Denver than in other areas of the state, but I doubt you'd have any problem if you don't look like you're trying to cause any trouble.
