It's that time of year again when brave souls take a frosty dip in the Delaware River at Neshaminy Park for the annual Polar Plunge.

The 5th Annual Eastern plunge takes place on Feb. 23 and will have people "Freezin' for a Reason"—to support local Special Olympics athletes.

Folks from Hatboro, Horsham and beyond can register either to plunge individually, or as a team at $50 per person. Teams must consist of a minimum of 10 people and requires pre-registration. Anyone can take the plunge. Participants younger than 18 need a parent or guardian's signature.

"The youngest plunger we have had has been 6 years old," said Nicole Jones, Special Olympics Pennsylvania's spokeswoman. 

Jones estimates that the oldest plunger has been somewhere in the 60 to 70 age range.

So far, 540 participants have pre-registered for the 2013 plunge, Jones said. 

If you're too chicken to jump into freezing cold water, you can still participate by making a pledge. If you make a $50 minimum donation for someone else to take the plunge, you'll get a "Too Chicken To Plunge" long-sleeved T-shirt.

Sportscaster Michael Barkann and former Philadelphia Eagles linebacker Ike Reese from 94WIP’s "The Mike and Ike Show" will kick things off at the plunge, and Philadelphia Eagles wide receiver Jeremy Maclin will participate in this year's event as well. He'll give autographs and meet and greet with plungers and spectators from 1 to 3 p.m.

If this is your first plunge, here are a few do's and don't's you should know.

The Polar Bear Plunge raises money so that children and adults with intellectual disabilities can receive year-round training and competition programs at no cost to themselves or their families through Special Olympics Pennsylvania.
