Don't know any of them, but wow, family has to be nuts by now.
UPDATE
It is with a heavy heart that I bring you the news.
Donald Masters has been found at a crash site on Rt 93 around mile marker 322.1 between North Fork, ID and Salmon, ID
Donald and his bike were spotted by Elk hunters that were out tracking a buck. There was about 150' of shoulder and then a steep drop off into a drainage irrigation ditch. The are was covered in thick brush. He was wearing his helmet.
Out of respect to the family and loved ones we will be closing this thread and creating a Memorial Page to Donald where you can share some kinds words with everyone.
My thoughts and Prayers are with the family.
Rest in Peace Donald Masters.
