- I don't know about moving MRI equipment, but high-energy physicists regularly
- move huge magnets from one place to another, leaving the old experimental
- area behind for the next person to install their experiments. We're talking
- anywhere from 10 KGauss and upwards to as strong a field as you can make.
- So I don't think this fellow's problem is unique.

- With this part, I agree.
