I remember back in the 60's and 70' that you could hire a sky writer and with white smoke (like clouds) he could write messages in the sky with his airplane. Some would fly a message over a girls house that would say "Will you marry me (insert her name)? Or it would say I love you with her name at the end. Or like if a store was having a grand opening they would announce it via sky writer. Being a sky writer back the was a real job. I remember seeing them in the sky. It was pretty cool to watch. Who would you like to write a message to and what would it say?
