Thank you BanksPhotos... frac sand photos

We visited iStockphoto yesterday and saw your great frac sand photos.  We decided to write an article about frac sand right away.


Thanks for inspiring us - and for the great photos.

And thanks for posting .. great feedback

I just now stumbled across this. Obviously, I don't check the iStock in Action forum too often. Regardless, thank you very much for your link, your use of my photos and for posting here.
