aerial rescue for bucket, training
I live in a small town in north central arizona. I have found that our sheriff depart as well as the sheiff dept's in the surrounding counties have a SAR - Search and Rescue and routinely train including aerial recue. You might want to also check with your local fire department. Also contact TCIA for references, as well as any of your local tree companies. Ask them , especially if they have been in business for a long time. Never reinvent the wheel if you don't have to. Other tree companies may be competitors, but you will find they can also be friends and helpful mentors.
