I can relate to hitting a badly set crab net. Did it last weekend. Too much loose line on top. Today got out there by 1 pm to sandheads and trolled where I saw jumpers, which was close in. Nothing. Commy trollers were there too and didn't get any that I saw either. I tacked out to deeper water and found nothing on the scope when I must have hit a school b/c my rod at 88ft went off and I had three in 10 minutes and was limited in 20. back in by 3:30 pm. My kids are the same, and want to bring the ipad out there fishing. I was out there yesterday with them and both my 7 yr old son and 9 yr old daughter played fish for awhile before loosing them to slack lines. They're still game, but want guarantees. Ha!
