Ha! Here's what I do besides relying on others to give it up...
Ask myself..."now Jim, where have the squids beds been in past years?"
Watch the sport boats counts and see target fish in any quantity or planned late night trips in the schedule.
And at times, when guys like Greg just won't give up what they worked so hard to find on their own...just before dusk, I'll scream out at home really loud so everyone can hear me at one time: "Does anyone want to go for a ride with me?" I always get crickets and closed bedroom doors...because they know that means I'm driving the coast in the dark looking for groups of poorly lit boats huddled together. And if any lights are green...BINGO! I'll then scan the area and ask myself: Jim, do you have the balls to launch anywhere near here to check this out in more detail?
And you wonder why some guys will always hook up and some just DON'T!
