Thanks for posting, my wife and I are going to check it out this weekend.
You're welcome! It's really quite lovely. Be forewarned, the botanic garden is smaller than I expected it to be, so do something else fun while you're up there (we ate lunch at the Native American Indian museum and then jaunted across the street to the Capitol for a tour). :3 Also, Penn Quarter Sports Tavern has awwwwwesome burgers! xD!
