I graduated in '99 and went to the convention in Orlando too. I was only in DECA my senior year and placed second in my state in the marketing division. I had a great time on that trip. Congratulations on being selected as a judge.
For any younger members who are looking for more knowledge to help them in any kind of business, DECA is a great start. Get involved in extra activities and definitely go to your local and state competitions and conventions.
