I went out to buy postcards to start mailing them around the world through the Postcrossing website.  It was so hard to find them. After checking a ton of stores, I found some at my local 7-11 at the mouth of Big Cottonwood Canyon.  I was so happy to find them so I bought a whole bunch.  I was able to send my first five postcards. One to Russia, Germany, the Netherlands, South Korea and Colorado.   I later found some at the marina at the Great Salt Lake. Here are some pictures of the postcards I found.  You are welcome to use any of these images.
