This is what I have as background on my desktop. It is a view of Downtown Albuquerque's Gold Avenue, at 2nd Street, looking east. None of what's in the picture was there just a few years ago. It used to be parking lots leftover from the Urban Renewal of the '60s and '70s. I like it because it looks dark, gloomy and urban, something which is in short supply in New Mexico, but which I love.
