Hundreds of Jeeps are expected to cross the Mackinac Bridge in the second annual Jeep the Mac this Friday.

Drivers will gather on April 21 for a "Blessing of the Jeeps" before crossing the bridge.  Drivers will then line up to cross the bridge to head to Mackinaw City, and then looping around to cross the bridge a second time and return to St. Ignace.

Nearly 450 Jeep owners took part in last year's inaugural event, and registration shows Jeep the Mac is on track for a bigger crowd on Friday.  Here's more from wilx-tv 10.
