I lived in Saint Martin and Biloxi several times since 2001 and was in Katrina.
Then you know my area - was in Ocean Springs (the county) until Gautier annexed us. Live south of Old Spanish Trail a mile or so East of where 57 dead ends (or used to before they put in the new high school and added some roads) at Old Spanish Trail. Katrina put 13” in the house and we we some of the more fortunate.
