Seeing "lots of deer" could mean seeing "lots of forkhorns & 2x3's" so you need to decide if that's OK. In CO, deer units are managed as either "Quality Units" where genetics are known to be good, and tags are restricted (sometimes REALLY restricted), therefore a guy has a chance to take an older age class buck; or a unit is managed as an "Opportunity Unit", where there are a relatively high number of tags and if you have a chance to take a forkhorn or other small buck, that's considered a successful hunt.
And that's straight from my Colorado Parks & Wildlife contact guy.
I figured that would be the case. We hunted in Idaho and saw 3 bucks the whole time (150ish 4x4s). It was an over the counter archery tag and any legal weapon tag during October but a controlled hunt from mid October through November. Buck to doe ratio was 35:100. With all the hiking we did going to glass in different basins, not one time did we jump any deer on the trail. It was pretty disappointing. Unlike our experience elk hunting in Colorado we would bump deer pretty occasionally and it was an easy draw unit with some nice deer there as well.
We definitely aren't looking for a 180"+ deer (although that would be great) but we don't want to shoot a small buck either; just something respectable. I guess in my mind I would I would relate it to the area I hunt for antelope hunting in Wyoming. We see lots and lots of bucks but the one we shoot are after we have looked over a bunch of antelope and they aren't monsters but nice goats.
Not trying to set my expectations too high and I know that some basins can be absent of deer, we just want a fun hunt that we can gain some experience in and potentially harvest a respectable deer.
Specifically speaking, we have looked at units 74, 75/751, and 82. Each unit "claims" to have 30+:100 buck to doe ratio. Its just so hard to determine if these areas are what we are looking for.
