On the way back from my brother's wedding in Vegas last week he stopped on the Hoover Dam and proposed! It has taken a few days to sink in, but now I'm just so happy and am really enjoying being engaged. My ring looks similar to this...I couldn't figure out how to get a picture to post, so I had to just attach a file. Hopefully this works.
Edited to say, if anyone knows how to post this as a picture, I'd really appreciate it.
