"I will be looking at where you are flying very closely. Please don't try this in public places or within 500m of any building / road."
Other than the weather here, this was my biggest issue keeping me from

I have over 30 acres of field in my back yard and a 2,800 ft runway at the club field
and still would have been disqualified by this rule.
