Old utility poles can be reused in many ways too, but they must be outdoors, and not where it can have direct contact with people. Back in 2003 I called a local electric company if they could donate a few used poles to be used as beams for a bridge I was constructing for a local park. They we're happy to oblige. You can sometimes see these poles used in retaining walls and buried alongside hiking trails, used as water bars. I keep an eye out whenever I'm on a trail and am sometimes surprised to see an electric pole miles from a trailhead.
