RE: telephone poles
As I understand the definition of right-of-way, it is not the utility companies land. A right of way is justa right to place utilities in a particular tract of land. For instance, I live in the country and my property extends to the center of the road that passes by my property. There is 33 ft right of way on either side for the utilities (includes power, phone, gas, etc). The land is still mine, but the utility companies have access to that land to place utilites.
Albeit there are instances where the utility company do own the land, but I imagine as long as its not a transfer station or something like that, the land is probably not the utility companies.
But the pole is the utility companies property and I imagine you cannot hang a stand from it, and as Kevin mentioned, not to mention how dangerous itis.
