I am an Oklahoma Delta Gamma alumni. I know there are several alumni groups throughout the state, and they do usually write recs during the summer for girls getting ready to go through rush. I looked it up, and there are DG groups in Enid, OK City, Norman, Tulsa and Edmond. If you want to PM me, I can either give you contact info for one of the groups, or I can get info from you and write you a rec. Good luck!
