More District Flags

Enjoying a day off from work, I took advantage of the free time and ample sunlight to work on my flags project some more.  I remember reading that when using a polarizing filter, your angle to the sun will make a difference in the result you get--and I totally see what they're talking about.  In some of my files (pre Photoshop) the sky is colorless and white, while in others, the Carytown shot specifically, the sky was a really deep blue.  I'll have to start taking note of where the sun is when I'm shooting.  On another note--I've searched online, and there isn't anywhere that I can find where these flags are marked like in Google Maps or anything.  Finding them is bound to get trickier as the list gets smaller.
