Don't give up!
It took me 5 years to shoot my first deer with a bow.
Sounds like you are in a good area.
I agree with moving your stands/blind farther down the trail, the way the deer were moving.
That will put them in front of you later when it's legal shooting hours.

Also, in a couple weeks the rut should be on and that will help you see deer during daylight.

We were all new at one time and I have been bow hunting for 20 years and still learn things every year.

Good luck!
Shoot your bow as often as you can so you will be ready when the moment arrives!
