Take a peak at the Molson Park venue page on Ticketmaster.ca. You'll see the Vans Warped Tour taking place there in July and Green Day playing there in August. They'll both be good shows because Molson Park is an awesome place to see a concert.
But wait a moment, didn't I attend the farewell concert at Molson Park? It was certainly promoted that way. The Hip said farewell to the grand ol' park and we departed with the memories. They were doing away with concerts because the land was being developed, or something to that effect, and the show was even dubbed "Last Bash in Barrie".
I think we were duped. It's two years later, and concerts are still being held at Molson Park. The value of my ticket stub has plummeted!
