Are you asking because you want to know if you need to bring something for velvet preservation for the rifle opener? I have had the same exact question before.
If so, I think you should look at the odds of a buck being in velvet on the 15th. I think the odds are low, probably around 5-10% that a mature buck will be in velvet in G or H on the 15th. Many do shed right before the opener, so if you are there archery hunting the odds go way up that you would shoot one in velvet.
