If you stop by the courts during the summer, you'll see a different demographic taking over. 

A group of senior citizens dressed in all white play with wooden tennis rackets to mimic a Wimbledon, tennis game. 

Jerry Sikora never played tennis until the day he decided to get a group together back in 1990. 

"It means a lot to a lot of us that don't do activities that much," said Sikora. 

Since getting the group together for the first time Sikora has gotten a lot of practice. 

He also added about 20 older adults to the team.

 The age range of the players is from the 50s to mid-80s.

"The older you get the smarter you get," said 70-year- old Ted Dasler. 

The group said they only get better with time. 

Sikora said the snowbirds get more practice during warm winters in the south.

"They have no mercy on us when they come back," said Sikora. 

Things can get intense on the court at times, but the friendships and entertainment brings everyone back to play. 

The players said the most important thing is to always have fun. 

More than 100 competitors of all ages and skill levels will compete for the fastest times on the recently updated track.

Competitors race bikes on a quarter mile track with several turns, jumps, embankments and moguls.
Track Operator, Rob Deede says they have competitors from age 5 to their mid-fifties.

"So it's a sport for kids of all ages, we also have it broken down based off of skill level, so from the new beginners, novices all the way through the experts who have achieved many wins in their career." Said Deede.

He says the oldest competitor he's seen was in his mid-eighties.

The track was revamped about a year ago to keep up with the changing style of tracks around the country and the world and to accommodate larger events.

He hopes to bring something positive to the community through the BMX club.

Races will take place this evening and the Championship Qualifying races tomorrow afternoon.

Admission is free. 

"Nope, commanders always eat last," Layden said with a smile Thursday afternoon.

Layden and members of his Army National Guard 173rd Engineer Battalion from Rhinelander were treated to a cookout, helping them fuel up for another week's worth of hard work.
