From the website:
Flora Zimbelman says it all started 54 years ago when she put an uncooked hot dog in her sister’s suitcase. [...]
Flora’s sister, Rose, found the hot dog when she opened the suitcase back up in Idaho, where she lived at the time.
"She mailed it back to me telling me to keep my garbage at home," said Flora.
The game was on.
In the years that followed, Flora would find a way to sneak the hot dog back into Rose's life. And Rose would find another way to sneak it back to Flora.
