Pictuers, hmmm....
For one, i dont mind any of it. Snap away cuz i sure do, some of best pics is when i used to use them throw away camers. I used 800 speed film & got killer shots on some'a the coasters. I got 1 shot on Wildfire perfectly upside down, it looks cool! Now we got a lil' video camera that takes pics also.
Dont feel guilty about takin' pictures, but if ya realize ya'r are gettin' funny looks, then i would ask.
