Wednesday Aug 06 2008 comments Camp Invention at Lincoln High School By: Gold Country Media Photographer, Karina Williams -A +A Joshua Wiegandt, 7, of Lincoln, and his partner, Britney Flint, 8, of Lincoln, finish a few more touches on their huge bumper car track they made at Camp Invention Thursday afternoon at the Lincoln High School. Very proud of his project, Christopher Pickett, 7, of Lincoln holds up his ?little roller coaster? he created out of used household items while at Camp Invention Thursday afternoon. Kevin Meyer, 6, of Lincoln puts the wheel on his very tall Ferris wheel he created out of a variety of boxes, cans, and other discarded items. Devin Lewis, 7, of Lincoln pins his ?tea cup? ride to the top of a can so it will spin around like the amusement park ride at Disneyland, during a project at Camp Invention Thursday afternoon.
