California over the last 10 years or so, has been going through an expedited replacement program for their power poles... I've done a bunch my self over the last decade.
Most of these replaced power poles that by the way are still in use date back to between the 1930's to the 50's.
Check with your local power company, they'll usually let you come in and cut the old poles into sections and haul them off for nothing.
