Breaking into commodities.

I graduated this spring from a top tier university that is more known for its med school than anything else. Due to personal obligations , I stayed at home in the south during summers working blue collar jobs rather than pursuing finance internships. I am really interested in commodities (especially Oil/Gas) and was wondering if anyone had experience breaking into this field out of school. I was a varsity athlete in college and have a relevant degree but am having a difficult time getting traction in my search. Any advice would be immensely appreciated.
