Highly doubtful... since it is something that has been on and off the table for almost two decades now.
The hard part is three fold. First there are too many opponents to gun rights to ever make enough folks happy with a national statute. Second, those who are pro gun rights are likely to not want to register for a national CC license... since they would view it as defacto gun registration.
Third, that power will remain with the states, since the Feds do not have the regulatory power to enforce a national concealed carry option in every state. Constitutionally it would still be up to each state to recognize it.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
