ok, thanx for clearing that up
The way you said it earlier made it sound like you were only required by the field to obey the AMA,
not that the field had its own 400 ceiling regardless of what the AMA said you can do


So you will obey new rules at that field cause that field will make you,
how about in the big picture, will you do so at other fields
that follow the AMA 'voluntary compliance' guideline (aka just not volunteering to comply) of upcoming regs?
(like if you go fly with Richard39 above)
