hey,my name is Drew and have been fishing for hali's in the surf for a few months now.I still think I am fishing empty water.If some one can take a picture or explain a little in detail about these troughs,how to find them ,and what to throw in them. my usual rig is a sahara 4000fd matched with a 7' volterous rod. I usually fish 8# test but moving to 6# floro. I fish sardine,white,and pretty much every other color LC 110 flash minnows. also what my usual is a split shot with a mosquito hook and small surf smelt. or a zuke super fluke (pearl white) drop shot. any info is greatly appreciated.
