I also must say I do not what is truly going on in Memphis but I have been through a similar situation in terms of staff leaving drastically. In 2006, days before our April Camp we lost our whole percussion staff and visual staff which led to a loss of almost our full drumline which went from 25 down to about 6 drastically. We marched with 32 members, qualified for semifinals in Division III and finished 9th place.
So I know what you guys are going through. Stay strong, don't give up, and I hope to see Memphis on the field this summer along with us and the rest of of the Open Class.
