While I can't stop the trespassers from ignoring my No Trespassing signs, I can continue taking steps towards hindering and discouraging them (and catching them and prosecuting them).
This is a basic drawing I did of the idea in my head to gate off my driveway from vehicles.
The bollards would be 6" diameter steel pipes filled with rebar and concrete sunk 3' into the ground with 18" to 30" diameter concrete base. Two heavy gauge wire ropes embedded down the entire center of each bollard sticking out the top. The first rope folded in half with the ends buried into diagonally offset ground anchors buried 18" deep and 12" in diameter. The second rope would be the barrier across the driveway. A short end on the left bollard, and a long span end on the right bollard. The 2 ends would be joined by a sturdy padlock. In the center of the driveway span would be a ground anchor and another wire rope to secure the long span from being lifted as well as providing additional strength.
The most expensive part about this will be renting an auger large enough to make the holes and handle my rocky ground.

The 3 dilemmas I need solutions for are:
- I need a better way to join the 2 ends than with a padlock. That will be the weak point. I still need to padlock it, but the tensile strength would be better if I could join the wire ropes together and if the padlock simply kept them together.
- I need a way to brace the bollards to stand plum till the concrete cures.
- I need a way to tension the anchor lines till the concrete cures.
Anyone have ideas?

here is how we built ours
Thanks for the link. Wish there were more/better pictures of the way the cable was attached to the posts.
It also made me realize that I forgot to describe my painting and flagging plans. I intend to paint the bollard posts a metallic silver using an enamel spray paint that gives a rough texture to it. Then I will paint over the top 12" of the bollard posts with the official "no trespassing" purple color. To make the cable as visible as possible, I found some bright orange reflective flags used to mark oversize trailer loads. I will string the cable through them. They will create a long row of large orange squares. The only problem I see is keeping the orange flags clean when the gate is opened, particularly over an extended period, since they would be in contact with the ground.

we looped the cable through the piece at the top of the left pole and doubled it back on the wire about three feet
we used wire clamp u-bolts like this to secure them together
we hammered the ends of the threaded pieces to mushroom them so someone couldn't unbolt them
We made another loop on the other end of the cable, the loop goes in between the horizontal pieces a the top of the right pole, there is a hole in the top and bottom and we have a heavy duty pin like this that goes through the holes and the cable
the pin has a hole in the bottom and we have hardened padlocks in those.
Honestly, the gate will only keep out good people, bad people will still get by, we have had several instances with people getting back there, but the neighbor put up game cams at each gate and we have caught all of them

Update: I went with a less expensive option than originally discussed at the start of this thread.
I used 2 layers of plastic tubing to protect the tree trunks from the cable.

Between the weather getting cold causing me concern over pouring concrete, the cost to buy the pipe to make the bollards, my very full plate, and getting quite sick recently (black mold exposure), nothing happened with the gate. I did actually bring in a company to quote me a real gate but since there will be a mobile to truck in there was no viable way to have a real gate prior to the mobile.
Then hunting season arrived and I caught 2 neighbors trespassing to hunt on video footage from the game cameras I setup for security. I've let multiple incidents of trespassing go, but its clear the neighbors have no intention of being neighborly.
I had the cable gate installed by Friday, and today I called the sheriff in. One of the neighbors could be identified to the property he lived on but I don't know his name and asked the officer to get it. He said he would, but following him out, he just kept driving rather than go speak to the man. Without a name, I can't prosecute.
