Sorry to disappoint you Rock, but that's the way it seems to me. Like I've said, been there-done that. It isn't very gratifying work as a climber. Think about it, you climb trees all day long near warehouses and train tracks (not the most scenic areas), you climb trees that belong to other people that sometimes are less than supportive of your cause, cars are usually parked under most of the street trees making every move critical in an un-pruned tree and you never get to cut a thing! What fun. And to top it all off, the thing you are looking for (and most times never see)is something you don't really want to find in the first place.
I'd rather be the subcontractor who can take part in this for the experience, but still gets to take a break and practice some hands on treework whenever you feel like it. Something tells me that the tax money would be better spent hiring subs in to do this from local areas to do this a couple days a week.
I did it for a couple of months and could not even imagine trying to drag myself out of bed every morning with that scenario in front of me. But, to each is own. Give it a try Rock.
