Any West TN nurses here working in OB?

Hello I live in the West TN area and am currently working part time (2-3 twelves per week) at a small community hospital in OB. I love my job and have no plans to leave, however I would be interested in working PRN in a larger facility, preferably in the same field, just for additional experience. Also, there are times when our unit is closed due to low census, and it would be nice to have something else to fall back on. Does anyone know of any OB/L&D/Maternal-Child opportunities in the Memphis area? Also, if you work at a particular hospital, do you like it? Thanks for any info!
