Hey Kathy Jo,
Online church for RCA, Evangelical Lutheran, CRC, United Church of
Christ, they tend to have the most MR churches in urban areas.
You could do the drive by on Sunday mornings but I imagine Cleveland
is pretty expansive. I would also call the local Inter-Varsity, Young
LIfe or other campus ministry groups. The directors of these groups
tend to know the most diverse churches in the city, and you'd get a
variety, some that aren't on the beaten path.
