I gotta disagree with you Todd. I live in Logan and watch that area every year as I fish in Weston regularly. That area has a ton of private and it is all posted. I watched five really big bucks last year all summer and talked to the landowner about getting permission. A lot of the landowners have a blanket "no hunting" rule because they are protesting IDFG management, so tons of the land never gets hunted. If you have access to a big piece of private land, there are some really big bucks there.
The biggest one I watched all summer hung out in alfala fields all evening, then bedded on public land, but you had to hike miles to get to the public land, even though it was only a few hundreds yards from the road, you just couldn't get to it easily. I hiked in there three times waiting for the buck to feed back up to public land, but he never came (I found out later he was seen with an arrow in his back a week before archery season started). There is a ton of poaching in that area, like all of SE Idaho.
I have two good connections for private land access, but neither allow any hunting at all, so I am SOL. If you have some good access...take it.
Look at Unit 73 success rates. In 2009, Unit 73 had 50% success rates and 55% were 4pt or larger. That is pretty good for guaranteed tags.
I can show you 10 deer in Unit 73 for every one I can show you on the Cache. It isn't even close.
