Looking for something a little out of the ordinary to do this weekend?

It's free, it's cool, and you can watch people #sendit on a giant ski slope in the middle of Civic Center Park: it's Downtown Open's free rail jam, happening on February 22.

Denver Westword announced the celebrity guests featured at the event, who include "X Games host and snowboarding personality Jack Mitrani,", who will host the rail jam. It also features professional freeskier and X Games gold medalist Tom Wallisch and dance producer SoDown.

Look for the giant yellow ski slope (the event is sponsored by Pacifico) and donate what you can, as funds from the event will go toward Civic Center Conservancy.
