Probably more fluke than anything with the gar.. I'd chosen the spot in search of flathead. Somewhere with patches of weed and plenty of sand, maybe with a gutter to hold some deeper water. If they're about you'll probably see the flashes of silver, cast by sight and you've got a good chance of hooking up. Having said that their are probably better ways to catch more gar if you only intend to bait them, using floats etc, but I just like the feeling of fooling them into eating a lure. They don't go particularly hard, but they apparently taste pretty good if you can get enough of them.
