From a reader:

JG,
The answer to Shannen’s question about how is it possible that Phil Connors could have procured tickets for Wrestlemania without leaving Puxatawney is simple, and I’m sure you already know the answer.
A town like Puxatawney undoubtedly has an AM radio station, which undoubtedly also has a Trading Post hour, where people call in and sell or trade items they want to get rid of. Surely, some guy must have called in offering his Wrestlemania tickets for cash or would trade for a waterbed.
