Definitions for "MBU"
Merit Badge University. This is a program put on by the local chapter of APO. It is a one-day event held twice per year at the University of Colorado. They arrange for counselors for several merit badges, some of which we do not cover with our list of troop counselors. There is always a list of prereqs. If a Scout completes these before MBU, he will complete the badge at MBU.
