I had the unfortunate experience whilst touring the west coast of the states late last year to travel with and trust a man in his 30's named Matthew Ray who claims to be from Alaska and says he has done 14 bicycle tours. I would recommend if you meet this man in the states, Mexico, central america or wherever else to NOT trust him. I lent him money to get his bike fixed and for food after he 'lost his bank card' then he went mia on me.
Wouldn't have been so hurtful if it wasn't for the fact I had trusted him and his exaggerated stories, he is a compulsive liar I suspect and it's hard to know if anything he says is truthful. I uploaded a photo, he is the one on the right, like I said he is not to be trusted and has already been banned from the warmshowers community, just thought I'd share this thanks.
