Steve,
When a few years ago, I was working with a GC, he hired a huge bucket for this old home in Orlando, historic district. But there was a lot of old plantings around the house and we couldn't really get close. It was 3 stories and we both went up in the bucket. It was extended as far as it could reach, all on sheets of 4x8 plywood and THEN tilted as far as it could go!!! We were around 30 feet up and he was measuring moulding and stuff and the little red light kept flashing and he said,, "oh don't worry, they all do this!". We finally got down and 2 weeks later, I found out a year ago, he tipped a bucket, with him and an assistant at about the same height! LAst time for me!
