T-dog, don't get me wrong, I have no delusions of granduer and doing big tree work. There are just several tasks around my place that I want to be able to get up in a tree and do a little of this and that (small branches etc)
I have a great relationship with an Arborist, (Joey) and when the going get's tough,, I back off and call him

, But, that said every big wind there are branches and odds and ends that should be done, that I do not want to call in a marker on.
Kids want a Zip line, son wants a higher tree stand, or big fort, I want a couple of limbs off this tree or that one, and besides that, kinda of like playing a guitar, or speaking a foriegn language, it is just one of those things I want to be able to do.
There are pictures of Joey taking down a big tree over my house on the AlB's house rework thread in the project forum. Then there are more of where I had him back out to drop another tree that dropped some limbs across vehicles in the yard.
I consider myself an above average DIY kind of guy, but there is always a time, like those trees in your pictures, that it is just best left to a professional.
