My personal observation of deer are not as plentiful as little as 20 years ago.
To much of the land has hiking and biking trails. Snow bunnies trashing
And not respecting the woods.
While I enjoy hiking like everyone else there's to many people
Developement encroaching more and more out.
I use to hunt Alpine areas, peutz Valley , Loveland outer areas, japatul, Jamul, and on.
A lot of it was BLM, NF but was sold or traded off. Thus my comment above. Surprisingly these areas still have a lotta of deer. But are now private or land locked.
