Unlimited Hydroplane fans will get to see some of the boats two months early as they scream down the Columbia River today. Jon Zimmerman and Jones Racing will bring their U-9 Unlimited Hydroplane to test from 9:00 a.m. to 5:00 p.m. today.  A few others boats, such as the Specialty Mobility 1-liter hydro, driven by the Tri-Cities' own Josh Culver will also take to the course for pre-season testing.

Boaters be advised, the river will be closed while hydroplanes are on the water.  The HAPO Columbia Cup and Airshow  is July 25-27 - get tickets and schedules HERE.
