The annual HydroVision International t-shirt giveaway has all but become an annual tradition, and event organizers are once more inviting attendees to vote on their favorite of four designs.
This year's choices pay homage to Denver, Colo., where HydroVision International returns to for the first time since 2013.
Shirts will be available on a first-come, first-served basis to the first 500 visitors to the PennWell booth, which is No. 338 on the exhibit hall floor.
HydroVision International is the world's largest event dedicated entirely to the global hydropower market.
This year's conference and exhibition takes place June 27-30 at the Colorado Convention Center. For more information about the event, or to register to attend, visit HydroEvent.com.
