Nope, but I understand your assumptions.
The US has conifers everywhere, and the link above is for a single collective of federally managed public lands, but does not include every other state-run and private organization that sells Christmas tree permits across the US.
If you can’t find yourself in any of the states above, it’s likely you live in a state with state-run Christmas tree programs. Texas, Oklahoma, any state not in the half of the US listed above will have other state resources for Christmas tree permits and many private tree farms, which are maybe 10 dollars more but offer the same service:
Buy a permit, drive there, choose a tree, chop it down, take it home.
Awesome, you got it!
I’ve also added the state programs information to my original comment, so I’m glad you brought it up.
I was kind of blown away when i first found about this and got into a long talk with a ranger who explained it all to me, so I certainly understand your skepticism.
Up until that point, I literally knew nobody who cut down their own Christmas trees, and now a few of my friends also get their own trees every year.
6 foot trees have fairly thin trunks, so all you need is any trail saw, I’ve even used a hatchet, and you’ll harvest the tree in a manner of minutes.
