Advice for hog hunting

I'm going hog hunting on Friday in west Florida (Sarasota County) and would like some tips on techniques/suggested things to bring/anything that will help me. I've been to this place a few times and have been unsuccessful every time, I'd like to change that Friday.

Here's how we'll be doing it: tomorrow afternoon, I'm going to the feeder to put out something to get the hogs rooting (hog wild or something similar) and then I'll be heading out to the feeder to sit on it for a few hours Friday morning. The last few times I've been out there I haven't seen any hogs on the feeder (even before sunrise and for hours after) except maybe a little piglet. I'd like to actually be able to shoot something this time. Hunters, can you help me out?
