CLEVELAND, OH – Who said there’s no such thing as a free lunch? They must not have known about today’s Walnut Wednesday in downtown Cleveland.

The only cost is a tweet.

Walnut Wednesday is every Wednesday during the summer from 11:30 a.m. to 1:30 p.m. at Walnut Avenue and East 12th Street. The event features more than a dozen local food trucks and live music.

Today, the first 500 people to show the Progressive Insurance street team a special post on Twitter will receive a voucher for lunch at one of the food trucks. Just tweet or retweet:

@progressive ’s @themessenger is buying me lunch with his savings at #walnutwednesday! #saveitfwdCLE

Any Twitter user who posts the hashtag #saveitfwdCLE will also be entered to win an iPad.
