I also use it to see the photos others have taken. Is this place really worth my time? Take Bingham Falls near Stowe. I've been there and and photographed it and I liked the location. But if I hadn't been there, I'd let Google Earth take me there. (It is really amazing, all the locations Google Earth has in its database.) Search on Bingham Falls Vermont and you will not only see the location but photos others have made there. Those photos may cause you move it up or down on your list of places to photograph.
Google Earth is one of the best scouting tools available.
I do a lot of night sky photography and use Sky Guide, an inexpensive app for my phone. I can put in any date and time and it will show me what's in the sky. I can see when the Milky Way rises and it's location in the sky. It is a great tool for the night sky. I'm also out at all kinds of crazy times. I made this shot http://www.goldimagesphoto.com/Portfolio/New/i-bwcLbgV at about 1:30 AM and this one: http://www.goldimagesphoto.com/Portfoli ... /i-vgHtJ9t at 4:00 AM.
So, to answer your question, I'm at least as crazy as you.
