Quite nice, nycfashion! I wear heels, too, although more for a bad ankle than anything else. But since I have to, I make the effort to ensure they're fashionable and tasteful with respect to the rest of my ensemble.
I live in Vegas, and get pretty much the same response as you do - very little, and what little I get, mostly positive.
As someone said, "perhaps I should have posted a picture." The words "guy in heels" conjures up all kinds of things, but when it comes down to the actual look, it's a non-issue.
If any lurkers out there are thinking about it, go for it - you'll be amazed at how you'll blend in more wearing heels than if you were wearing a stylish hat.
