I imagine a good portion of Oppo has already seen the posts, but in case someone else in the Sac/Sonora area hasn’t, copying the latest details below. In short; a rider/enthusiast, Davey Johnson, is missing & last located near the Sonora pass area on Wednesday at ~ 8:00 AM.
If you have any information contact the original poster &/or the authorities noted in the Facebook post linked. Ride/Drive safe out there Oppo.
Update: Sounds like they found his bike at a rest area on RT-49 by Mokelumne Hill, CA. Still no sign of him though. If you’re running through there tomorrow morning keep an extra eye out (also sounds like a S&R is planned tomorrow morning in the area to try and find him)
