I just got kicked out of flying at a lake close to my house. The area I was flying is a public access area but nobody was there. Because of recent flooding there are a lot of COE people about. Anyway one saw me flying and told me I couldn't fly there. He was a little unsure so he went to get another ranger. The second one was definite on it and gave me a brochure. They quoted me Title 36, chapter 111, part 327.4, aircraft. When I read the brochure closely, paragraph b said flying was prohibited except in areas designated by the District Commander. Paragraph c, though, indicates you van fly but not in a reckless manner. My question is whether a COE lake is a no fly zone? I see planes and helicopters flying over them all the time at a higher altitude. I'll probably write them for clarification. If I stick to their rules, a lot of public access land in my area is now off limits. I'd appreciate any advice anybody could give.
