The Michigan Department of Transportation and the Mackinac Bridge Authority are asking members of the public to share their Labor Day Mackinac Bridge Walk experiences on social media with photos and videos.
One of those who share a memory will be chosen at random to receive a tour to the top of the Mackinac Bridge.
Last year, Michael Gronseth of Negaunee was chosen at random to win a free tour of the bridge.
Members of the public are invited to post memories through September 9, 2013 of walking the bridge, either this year or in a previous year, on Instagram and Twitter using the hashtag "MightyMacWalk13."
Facebook postings won't be considered.
This year's walk is shaping up to be quite exciting. Governor Rick Snyder will lead around 40,000 walkers across the 5-mile span beginning at 7 a.m. Monday, September 2, 2013. Walkers can start across the bridge up to 11 a.m., and buses are available to bring walkers from Mackinaw City to St. Ignace for $5.
To help ensure the safety of all participants, the Michigan State Police will be conducting searches of purses, bags and backpacks for all walkers. Walkers are asked to leave their purses, bags and backpacks in their vehicles if the contents aren't essential, to avoid delays.
