I also realize that there are more factors then just sparing the spikes that has improved our deer numbers.
1. number of hunters ( been down in VT)
2. weather conditions ( too warm- deer don't move)
3. good winter - less snow ( sometimes this can also hurt deer, once they get below the browse line, there is no way they can get above this area without snow)

If everyone was on the same page in regards to letting smaller buck walk, it would greatly increase the size. The problem is how some hunters look at the issue. They may feel that if they don't shoot, someone else will (I'm not looking for an arguement here). I don't blame hunters from taking a legal buck or doe.
Just a thought.
