As another cold weekend approaches you may be prepared to bundle up and stay inside this weekend.
That's the plan for over 800 lacrosse players as they converge on Broome County.
The 5th annual John Mack Southern Tier Shoot Out Lacrosse Tournament starts Saturday morning.
John Mack was killed four years ago during a lacrosse game after taking a stick check to the chest.
It took paramedics 19 minutes to respond and use a defibrillator to restart his heart.
The 17-year-old Binghamton High School junior died three days later.
In his memory has come a huge event in the lacrosse community.
Tournament director Rob Mack says, " This is the largest indoor tournament in the country, that we know of. I've talked to many other tournament directors and other coaches and none of them have ever heard of a tournament with 60 teams in 2 days. One of the reasons is we have this facility where we can fit 5 fields that we can play almost whole field lacrosse, which is pretty amazing."
Games start Saturday morning with players ranging in age from 10 to 70.
Proceeds from the tournament are used to purchase defibrillators for area sports organizations.
