This weekend marks the fourth stop of the 2013 Maple Leaf Monster Jam tour as the tour makes their way to Budweiser Gardens in London, Ontario for three shows – two on Saturday and one on Sunday.

The first stop in Toronto saw Jim Creten in Bounty Hunter pick up two racing wins, while Cam McQueen in Northern Nightmare and Jon Zimmer in Grave Digger split the Freestyle victories.

The second stop in Vancouver brought a racing win to Team Maximum Destruction and Kreg Christensen, while Zimmer took home a second Freestyle victory.

Last weekend in Edmonton, Zimmer picked up four more wins (three racing; one freestyle) while McQueen took home two freestyle victories.

Heading into London, Ontario, Zimmer and McQueen are both looking to add more wins, while holding off the challenge from Chris Bergeron, Brad Allen, Bob Robbins and Peter Robbins.

Zimmer, who holds three racing and three freestyle victories so far during the Maple Leaf Monster Jam tour, is in his first year as Grave Digger driver. With seven years of driving experience and being previously invited to compete as part of World Finals, Zimmer earned his right to be on a team that enters their 31st year of Monster Jam competition.

Zimmer got his start in Monster Jam by crewing in 2000, before beginning to drive in 2005.

Meanwhile McQueen, who holds three freestyle victories across the tour so far, has already proved his strength as a Freestyler, capturing the 2012 Monster Jam World Finals Freestyle Championship. It marked no surprise that he won the 2012 Freestyle Championship as he came close in 2011, losing in a tie-breaker to Jim Koehler.

McQueen got started after filling in for an injured driver at a show.

"I volunteered at shows whenever they were close to my area," McQueen told MonsterJam.com. "I helped out by cleaning trucks, loading trailers, and doing whatever else they would let me do. My first driving opportunity came about when another driver was injured and I was asked to fill in."

McQueen originally drove the Nitro Circus truck and has been competing for five years now.

Zimmer and McQueen will be joined in London by Team Scream Racing teammates Chris Bergeron and Brad Allen.

Bergeron, a thirteen year veteran, is excited about bringing “Brutus” to London this weekend.

“Been a couple years, been four years since I’ve been there, but looking forward to there and having some fun,” he said. “It’s a nice little venue and we love coming to Canada. Come there probably 10 times a year, the people are always friendly. It’s always fun to race there. The fans are awesome. It’s kind of our home away from home.”

He got his start in Monster Jam through his friendship with Jim Koehler. His full story can be read as part of the interview I did earlier this week by clicking here.

Meanwhile, Brad Allen enters his first season driving Mega Bite as the truck was debuted last year at World Finals in Las Vegas. Allen got his start in Monster Jam crewing for Koehler and Bergeron.

The last two trucks making the trip to London are Aftershock driven by Bob Robbins and Krazy Train driven by Peter Robbins.

With an exciting line up of drivers and the excitement of the Maple Leaf Monster Jam Tour continuing to build, this is another event that is a must see on the tour.
