Ha...i already thought of that one....
but just saw through one leg , and leave the sawn piece in place with a long wire to my Jeep....
Illegal as specified by Prawo Lowieckie.
However, the same Prawo Lowieckie (Hunting Laws) states the following:
Art. 12. Dzierżawcy i zarządcy obwodów łowieckich mogą, po uzyskaniu zgody właściciela, posiadacza lub zarządcy gruntu, wyznaczać i oznakowywać zakazem wstępu obszary stanowiące ostoje zwierzyny oraz wznosić urządzenia związane z prowadzeniem gospodarki łowieckiej.
Art. 12. Lessee and administrators of hunting areas may, having obtain permission from the owner or from the administrator of the grounds, define and mark as inaccessible the areas inhabited by game, and to erect structures associated with with hunting (industry/activity)
Now, I'm not a lawyer so there may be a catch.
But... I am sure that, as and owner of the ground you can travel fairly close to those towers. I also hope you still have your Harley. Use low gear, rev it up as soon as you notice some action on the ambona. One of those 5 million candle spot lights (inexpensive) will make it easier for you to see from afar at night. Who knows, you might even spot a deer or a boar running away from the bright light.
If for now other reason, I would do just that to make sure I am safe with someone at the edge of the forest. Heck, I'd even care about the fellow human being up there on he ambona. Drive up a few times and offer beer. At 1.30 am. Sing a drinking song, Polish or English.
If you want to be a little less noticeable get the cheapest pay-as-you-go cell phone. Ideally two. Place them around the edge of the forest. One around the edge of the forest, the other about 30 to 50 meters deeper. Make sure the ambona and the cells form a somewhat straight line. Call one when the hunters show up. Then call the other phone. Just two signals. Perhaps even just one. On an off. Then pause. Observe if the hunter is looking for the source. If so, stay low. Give him 30-60 minutes, let him get his confidence back. If he's climbing the ambona for whatever reason give him a ring too. He won't be able to located the direction with his back to the source of the sound.
You can experiment with the location of the phones. Who knows, perhaps the triangle arrangement would be better. Perhaps placing one on the ground and the other up on a tree would create an even more confusing effect.
Oh, make sure the phones are light-tight as to not be seen at night should they emit light when ringing, and that the ringer is set to high. Heck, you could even use one of the custom custom rings. Only your imagination is the limit, but in the spirit of age long Polish tradition I'd suggest speech sounds such as "Spierdalaj", or "Ty chuju". Use native speakers, of course.
