I see. So you are comfortable flying at 400 ft AGL within 5 miles of airport (assuming that you are working under current Section 336) rules, and can't be bothered to notify the airport. You may or may not be in luck when the new law is codified - possibly you will be in uncontrolled airspace and won't be breaking the law any more.
Most of the time I'm down low or just about the trees - I can only really see it well when it's at 200 feet , but, sure, I'll go to 400 feet once in a while. I've never even seen a plane when I had the drone out.
