The Salvation Army has sent canteen trucks to feed people in Fort Myers. I don't know how much goes to first responders vs residents. I'm with you not trusting many of the big charities, but the Salvation Army keeps its admin costs really low and has a long history of disaster assistance on a global level.
Our family has long supported them. When my parents arrived as refugees in New York Harbor on a cold November day in 1950, the Salvation Army was there with hot coffee to greet them. It was their first cup of coffee in America, delivered free of charge. My parents never forgot how they were welcomed to the new world where they were starting over with nothing.
Haven’t given to the salvation army since the racist leftist diatribe i had to sit through to volunteer to help with Katrina evacuees. Along the lines of being in Katrina was akin to being on a spaceship on the middle passage and whitey better bow to the darker skinned evacuees and not upset them. Walked out and never gave another dime to the salvation army. I give to Samaritans purse. Franklin Graham is u abashed and unwavering in his preaching of the Gospel
I support:
Samaritan's Purse,
The Cajun Navy,
Team Rubicon.
YMMV
