Fairly new to the forums here, but not to Eastman.
I have applied in years past, for NR preference points in Colorado. I went a few years without applying for them. I checked the website but cannot locate any info on whether they expire or lose them if you don't apply for them every year or couple of years.
It varies by state, and have points accumulated in other states as well and each state is different. I emailed the Colorado Division of Wildlife last week for information on that, but did not get a replay. Before I call them, I thought maybe someone here may know.
