FYI... This is most likely NOT Pasco Fire Fighters (which are funded by tax dollars). This is a scam charity that is going to take 99% of your donation as 'operating expenses' and then give the 1% - if you are lucky - to some charity. Ask him for his FL charity registration number, and then look it up before committing ANY money.
Previously he used bacff, now he's using CNAM=FFBOF.
If you have a volunteer department, call them directly and donate if you want. Otherwise, stay away from scammers like this.
