RE: AMA or Private?
The fact is, a club becoming AMA makes the most sense for the land owner! How large a shovel do you guys use, when you determine your going to make a mountain out of a mole hill? Yes, pay attention to land use laws or other applicable laws! However, my guess is these laws are somewhat dfifferent (simpler), in Hampton, Iowa, then they are in Los Angeles, California!
I have seen or heard of flyers (people I actually know) of all experience levels becoming seriously injured when they unknowingly and unthinkingly stuck a body part into the prop arc! One would have bleed to death, had it not been for the quick thinking of his flying buddys that day. Just this fall one of my flying buddies was adjusting his carb and stuck a finger in the prop. By the time I got him to the hospital, he said he was feeling very light headed. I feel I have been lucky, for 41 years, I have not been seriously cut by a prop. I've also been in the machine trades for 28 years and not been injured, still, it only takes a single moment of not paying attention!
