This cache is very close to our house in a suburban area of Vienna, basically in a little village called Neu-Suessenbrunn. My 10 years old son hid the cache behind a power pole next to the street (public space), on the ground, in a waterproof metal box. It is to be noted that the poles for power lines here are totally safe, i.e. they have a concrete base and then a wooden trunk for the pole itself... so no danger of electrocution. The size of the cache is medium.
