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.
Understanding wind currents and thermals in hilly, broken terrain can often be incredibly frustrating. I've found that collecting and storing milkweed seed pods during the late summer has made me a better hunter in the bluff country that I hunt. These little feather like seed dispersers will float on the lightest of air currents and will show you what the wind is not only doing right at you're location but more importantly down range. I like to use the off season to float them...
