It's the Wacky Races. It's Cannonball Run III.

No, it's just The Gathering.

More and more, those Baltimore food-truck rallies known as The Gathering are meeting not just on Fridays but two or three times over a weekend. Food trucks will be rallying three times this weekend - in Mount Vernon on Thursday, on McHenry Row on Friday and in Canton on Saturday afternoon.

The Thursday night Gathering, a first for Mount Vernon, is on the parking lot of the Maryland Historical Society, 201 W. Monument Place, from 5 p.m. to 10 p.m.

The regular Friday night rally returns, for the first time since July, to McHenry Row in Locust Point. That's from 5 p.m. to 10 p.m., too. This is a special Oktoberfest-themed rally, with live music and a beer garden.

Saturday's Gathering, a fundraiser for Lyme disease awareness and prevention, is in Canton, at the Coppermine Du Burns Arena, from 4 p.m. to 9 p.m.

Admission to the rallies is free but all-you-can-drink wristbands are sold for each rally on The Gathering's website.

Baltimore's first food truck rally, back in June 2011, was held on an empty lot on Central Avenue. The second Gathering was held two months later on a parking lot in Fells Point.

Soon, The Gatherings, which are produced by Damian Bohager, were a monthly thing. And then they became a weekly thing, rotating on Friday evenings among fixed locations in Hampden, Little Italy and Locust Point.
