I was removing a major cracked limb from a Box Elder on Monday and climbed a Linden next to it to access the cut. Another company had done the pruning of the Linden (as well as a Norway Maple) a couple days earlier. My client (the folks next door who have the Box Elder) asked me to look at the work and I was shocked to find they had 1.entered the tree via a STEP ladder (first limb was @ 6' up) 2. SPIKED the central trunk and did the pruning from there with a pole(clearly with only spikes and a lanyard)! I had heard about these types of folks but have yet to see it first hand! I hope these folks do some research soon and learn the error of their ways.
