I have multiple Ostara's... Saturday the 16th with the Novitiates of the Old Ways; Tuesday the 19th with the Wiccans at New Castle Correctional Facility, and Tuesday the 26th with the Asatru at NCCF. And my personal observance on the 20th. I will also be with the Asatru at Wabash Valley Correctional, but don't yet know the date.
peace,
ES.
