If there are does around, the bucks will be close by or at least checking on them. The term you're call hooking, I believe is what we call rubs or sometimes horning. Check small to mid-sized alders near trail, creek, or road crossings and/or small to maybe 5 to 8 inch conifer
Fishnfur is spot on If your hunting does, bucks will show. I do prefer to hunt where I see good rubs, (hooking or horning, its all the same to me. Just dont say scrapes, i have heard several folks refer to rubs as scrapes, totally different use of words to me ). however having good fresh rubs does help with the confidence as I feel like rubs are often made closer to a bucks core area. If your hunting just rifle, i would stick with the aea you know deer are, if you are looking for later seasons I personally would put a little more effort to finding rubs. With regards to rubs my experience is that although a big buck will often tackle small trees, the opposite is not often true. This goes double if the tree is a "Unbendable" conifer, big cedar rubs IMO are made by the most dominant bucks in a given area.
you probably picked an area that only has female deer
Its tough passing up a legal buck but let them spikes go, Good Job
As an afterthought on your trouble finding buck sign, my initial thoughts were that there are just fewer deer than you have experienced in other areas, but I did not have the data to discuss it. The entire Blacktail population in Western WA is estimated to be 90-110,000 animals, of which only roughly 20% are bucks - call it 20,000 bucks for the entire west side of WA. http://www.wafwa.org/Documents%20and%20Settings/37/Site%20Documents/Working%20Groups/Mule%20Deer/Range-Wide%20Status/2015_Black-tailed%20and%20Mule%20Deer%20Status%20Update.pdf That small humber of bucks likely spreads out each individual buck's territorial rubs and other sign, and results in small areas of activity in any given larger area, making it occasionally difficult to locate rubs. I'm not sure where you hunted before, but I've got a feeling the deer populations were quite a bit larger, which ultimately increases the amount of buck sign in the woods. Once you get familiar with typical areas that BTs rub, it becomes less of a chore to locate rubs.
