One of two C-SPAN campaign buses are making a swing through Bend today. Residents will be able to walk through the bus and see how modern presidential campaigns are run, and what it takes to bring that campaign into your living room. The first stop will be at Bend Broadband offices near Empire and the parkway from 8:00 to 10:00 a.m., then it will be at the Cascade Village Mall from noon to 2:00 PM today only.
