One of the highest Blood Alcohol levels I ever saw  was this huge Klamath Indian arrested for perforating his wife's trailer house from the inside with a .22 rifle down in Goshen.

He was so big that the OSP officer, with the guy cooperating (as much as a drunk can), could not get the handcuffs to go around his wrists even when at their widest.  

He blew a .38 BA.  

He probably woke up legally drunk every morning and then started drinking.
