Fester: an outfit called Pennington Tree Company, but I would imagine there's lots of graft and corruption and you-grease-my-hand-and-I'll-grease-your's going on with the park and the other contractors. It's called politics.
Do you have evidence of this? Have you asked the park who is paying for the cutting? I know for a fact that at some Civil War parks the funding is paid for by private individuals who donated money for the specific purpose of restoring the parks to wartime conditions. I've posted excerpts on this thread by the men who set up these parks including the Secretary of War telling how they want to restore them to what they looked like at the time of the battles, as well as a statement saying that the park was not for love birds and recreation but rather for remembrance and study. Yet you still persist in making scandalous statements about their motives.
Gettysburg was not made into a park for your daily walks and commune with nature. It was founded to memorialize those who have fallen and for future historians and military men to study.
