I remember seeing the big old trees at Gettysburg. When you look up the trunk of the tree, you see the bullet holes, still bleeding from the lead balls, inside. It would be terrible to cut down these trees.
I don't think those are the trees they are talking about. I think the Park Service is removing trees that were planted after the battle. If they have bullet holes I'd think that's a keeper.

That's not the trees being cut down. The post indicates that the park service is planning to cut trees that have grown since the time of the battles. This doesn't effect what trees may have been there at the time of the War.
Nobody is talking about cutting down trees that were there during the battle. ("The park service plans to make the landscape look like 1863 ..."
