i saw a guy hitch_hiking trying to go north on 1-5 near on the exit 105. He had a rucksack and brown/orange hoodie. Looked pretty young. didnt look too dirty either. not sure if your son matches that description
Thank you Everybody for all the help, Prayers and Information. I found my son and he is ok, he was just scared since he had gotten into a little trouble, but apparently he did have quit an adventure while he was up there and I think this was a good thing for him. Once again THANK YOU!
