I hunted it a few years ago on the PIW tag. Took five trips down there, two scouting trips, once during the muzzleloader season, the early rifle and the late rifle. Saw lots of bucks and a three real nice ones, but just couldn't get it to come together.
Saw 56 bucks the last five days of the late hunt. Was holding out for a hog and ended up killing a 160is buck the last half of the last day. Saw three big bucks, but couldn't get them to hold still long enough to size them up or put the stalk on them. Oh well, you roll the dice and sometimes come up a little shy.
You'll see plenty of bucks, as for a monster, even the guides need a little luck! I was camped next to two guides with their clients and one killed a pretty buck (not a monster though) and the other went home empty-handed, so a guide don't necessarily guarantee anything, although if you don't have time to learn the country they at least bring that knowledge with them.
Good luck, I'd sure like the tag again!
