Have an OA team do your Crossover ceremony!
One service the Order of the Arrow gives to local Cub Scout Packs is to hold Arrow of Light Crossover Ceremonies. Arrowmen will congratulate recipients for their achievement and welcome them to Scouts BSA.
By creating a memorable experience for the incoming scouts, Crossover ceremonies conducted by the OA inspire them to become dedicated members of Scouting and to one day join the OA themselves. Contact your Chapter leadership to schedule an appointment, and they will be happy to help you.
