The showdown between Lansing area firefighters and police kicks off this morning with the start of the Battle Of The Badges Blood Challenge.
You can help decide who wins by rolling up your sleeves and giving blood today to the American Red Cross.
Blood donations take a dive during the summer months due to vacations and other activities, which is why it's important to give right now.
Police won last year-- so the firefighters are hoping to take home the bragging rights this year.
To particpate in the challenge stop by the Marriott University Place in East Lansing on Albert Avenue today from 11 a.m. thru 6 p.m.,, the blood drive is on the second floor.
Everyone who donates today will get a free Red Cross t-shirt, sandwiches from Jimmy Johns, and be entered to win tickets to Michigan's Adventure,, or the next Nascar race at MIS in August.
