Searching For John Riley

Hey everyone, I'm looking for help from people with drones that could help search in various places for John Riley. He's been missing the past few days and his family is in need of help locating him. He was last driving a Ford truck with utility bed like seen in the photo here. Some locations we want to look are out Garden Valley Road where the road is close to the river going all the way out to Tyee. I circled some spots that would be good to drone over the river and the boys and I might be able to get to some of those locations. Another is the Callahan's. He had a job out near Whistlers Bend Store, so not sure if might have traveled along North Bank Road? If so, that stretch of road near the river could be good to drone as well. I believe he had a job out in Sutherlin as well. If anyone else has any ideas of areas that would be good to look, please add them below. Thank you!
