IF you have hunted 54 2nd season before and you can invest a lot of scouting time before the opener, you are realistically looking at 170+
IF you haven't hunted 54 2nd season before and you can't scout much before the season, you are looking at 169-, unless you get really lucky
IF you do get the tag and you hunt it, you will see why the buck quality isn't recovering very fast.
You will have a lot of company during 2nd season. My advice would be to get away from the roads. There's a lot of country in that unit that will provide you the opportunity to get away from the crowds, which will also improve your overall experience.
I am no expert on unit 54. This is just my opinion based on the time that I have spent in there the last three years. The local guys may have different advice to offer up.
Good luck with your decision!
