I have sent smoked fish from Washington to connectiut and florida and it has been rcvd in good condition and still good. For the brine do some searching on this website for a good brine mix. I have never tried the Luhr-Jensen brine but you should experiment with others my next brine is going to be a dry brine I here good things about them.
