LNT has its place but like everything it gets taken waaaay too far and when someone actually comes up with scientific proof that screwing those spikes into trees is more damaging then straps then we have something to go on. You cant just look at it and say see that screw just looks mean and hurtful. They tap maple trees in much the same way to get the sap every year and have been for a long time and those trees get reused every year. So who is to say the straps are better? More yet if everyone found out that the only way to not damage the tree was to go back to sleeping on the ground would YOU make the sacrifice to save the trees?
