The back parking lot can be used. Just be aware that the lines delineating parking spots are somewhat obscured by dirt.
The side lot for staff/handicapped parking (across from the side door) can also be used. In order to allow enough room for two-way traffic, please park parallel to the retaining wall (as the truck below is doing), NOT head-in. There should be room for three cars in this area.
Remember that you can always use the new, additional parking lot behind Grace Counseling Center, next door to Grace Church.
