I know what you mean, Julie...I try to be inconspicuous, but I have missed some great shots because I was shy to take them. I guess you just have to go for it and take the chance they won't mind...and make sure you can run fast, lol.
Thank you, I am happy that I got this one. I always feel so strange taking pictures of people I don't know. I kept trying to pretend I was taking a picture of something else. I always feel like I am invading on them.
