What took your job from an hourly thing you punch in and out on and live for after work hours to a totally encompassing love that you have for this job? Was it when manilla was replaced with synthetic lines, the camming lanyard was invented, the taughtline turned into the Blakes, the pole chainsaw, gas powered drills for cabling, Alex Shigo seminars, tree forums like Treebuzz (you cannot be successful without forum to stay current), slack tending climbing systems, SRT, crane td's, whole tree chippers, mini skids, Wraptors, climbing contests,....big money to buy toys...?
I have seen SO many innovations in the many years in the biz. I go back to manilla turning into estralon/nylon climbing lines. Big improvement as even tho the manilla was a great line for ddrt, you always were leery about heart rot. But with the advent of nylon it was an issue that the taughtline kept "rolling out" creating a very dangerous situation. Enter the Blakes, enter the camming lanyard, enter the slack tending, enter mechanical hitches, enter SRT.... But innovations be what they are, I still prefer descending on a Taughtline hitch to any modern day hitch cord or mech. hitch set up. It just feels better and is more responsive imo. It fills up my palm. Self tending is important enough to make that irrelevant tho :-( Beats pressing your shoe sole on the standing part of the line to advance the hitch...often requiring 2 hands).
Everyone that wanted to learn arboriculture read PP Pirone's "Tree Maintenance" nightly and memorized and referred to it (also his "Insects and Diseases of Ornamental Trees")...Wise Garden Encyclopedia..., enter Al Shigo, enter Richard Harris, enter Schwarze, Mattheck, Luly, Dirr, Urban, Gilman...
