Favorite subjects to photograph

I know a lot of people are more random about this, shooting pics of whatever grabs their attention. But does anyone have particular subjects/items they love to photograph more than others? My loves are vintage architecture, decaying building structures, and street art. I'm drawn to the craftsmanship of old architecture, and the fact that both the old buildings, and the street art are susceptible to the environment, and could vanish. Any favorite subjects for anyone else out there?

I tend to like to photograph nature. I most love taking pictures of rocks, minerals and crystals. I also like to take pictures of flowers and trees. I use these photos often in my 3d art or modify it in some nifty way to bring out even more of the beauty. This is why I need a good macro mode camera cause I take lots of close ups of flowers and minerals.

Well I'm pretty new to photography but I really really like taking pictures of the Los Angeles skyline or any city skyline for that matter.
