I heard from Jacob again tonight. He found out today that he will in fact be heading to Fort Leonard Wood tomorrow! We're very excited that he will get to do his training where he was supposed to be. He should be starting OSUT (basic and advanced training combined) on Friday!
He sounded tired on the phone and said he's not getting a whole lot of sleep. He also has what is commonly referred to as "the crud". Most people get a cold during basic training and it hangs around for a while due to the lack of sleep and intense physical exertion. Hopefully he feels better soon!
