Another 'sign' of thanks is going up in Prineville. Today, around 8:30 a.m., another World War II Veterans Historic Highway sign will be installed near the Prineville Airport. Dick Tobiason, Chair of the World War II Historic Highway Committee says the Prineville Airport played a very important part in the war effort. "They trained about a hundred pilots in a little over a year. It was marvelous because the airport was built for that mission. There were buildings downtown, for housing the student pilots. I think they had four barracks. They could house 100 all together. And they built hangars there. A matter of fact, there are still two buildings still in use today. One is a hangar. And ones' another maintenance building but they're leftover from World War II." Tobiason says these will be the 15th of the 19 signs to be placed along 325 miles of U.S. Highway 97, State Road 39 and State Road 126. The signs hold a dual purpose: to thank the World War II vets and to educate the public about Central Oregon's contribution to World War II.
