I took some pictures at a couple of concerts with my Nikon Cool Pix 3100. The pictures came out decent, if I knew how to post pictures, I would. Anyway, I liked it because I could see how the pictures came out after I took them and delete them when necessary. Lindsey is easy to take pictures of, Stevie, a little bit harder. I think it might have something to do with her lighting. A good tip that I was given after my last show, when using a digital, look through the viewfinder instead of using the display. It should help when trying to steady the picture. And if you use the best quality setting on a digital, you don't have to worry about the distance thing as much. You can take the memory card to a place like Wolf and zoom and crop the pictures. But from the 2nd row, it shouldn't really be a problem. I was in the 5th row in West Palm taking pictures and I was fine.
Security you will have to feel out. It all depends on the venue. I was so scared trying to get my camera into Mansfield and they didn't even pay any attention when "looking" in my purse, which was really small and the camera was pretty obvious. Other venues, like Jacksonville, clearly state no cameras and I would be a lot more careful places like that. I would say don't use a flash. I didn't need one and I know my friend didn't either. Plus, it annoys the heck out of Stevie especially.
I wish you lots of luck and I hope you have a blast at the concert. I hope you will report back for all of us who don't have anymore concerts to go to

and share any pictures that you get!!
