fully remote controlled station on the mountain top (500 meters above sea level)

I got up with the chickens and went to bed with the owls every weekend since November 2009 to build up this station on the top of the mountain. So when I came back to my home at night, I was a whipped puppy. However I finally completed it in September 2010.!! Only a loony guy could make it. A loony guy made a loony station at last. So I am as happy as a dead pig in the sunshine now.yes


Chaque week-end depuis novembre 2009, je me réveillais très tôt le matin et me couchais très tard le soir pour construire cette station sur le sommet de la montagne. Alors lorsque je revenais le soir à ma maison, j'étais épuisé.  Quoiqu'il en soit, je suis tout de même parvenu à la terminer en septembre 2010.!! Seul un type fou aurait pu le faire. Un type fou a construit une station un peu folle. Donc j'en suis très content, et je suis heureux maintenant.
