"It just became an occurrence that he liked and so she's got the 40 years, and then if you turn around Alan, the back of it says 'Alan's Hodag Hotties,'" said Barb Vugrinec.
Alan's sister says he has 11 other shirts from previous years. She says Alan always has a blast at the festival.
"So he's been here every year, I have a camper and he camps with us. He just loves the comradery with all the wonderful people out here and he has a great time," said Vugrinec.
This year was extra special for Alan. He turned 40 this year, and it's also the 40th year for Hodag itself.
