The posted coordinates are bogus unless you want to go to the 50-yard line at Memorial Stadium.
I was at one of the local trade days and stumbled across this LITE BRITE children's toy. You may remember seeing one - it looked like a computer screen filled with round holes where colored pegs could be inserted. A 25-watt bulb behind the screen allowed the neon pegs to 'glow', creating a bright light picture when complete. Very entertaining when you are a child and a real source of vacuum cleaner clogs when you run over the neon pegs that were always laying around.
This particular LITE-BRITE had a picture displayed and I saw coordinates in the image! Sure enough, this led me to a cache that I will now share with you. If you can't see the coordinates, well, just enjoy the picture. Otherwise, go find this cache and claim another Mystery smiley!
