RE: bad rc flying fields
I've flown at many different fields through the years and when visiting an unfamiliar field I make a point of looking around for any posted field rules or procedures unique to the field that I should follow. I also make a note of where and how to comply with transmitter pins, tags, or impound procedures.
Finally, and perhaps most important; I declare myself to the other flyers that I am an experienced flyer but new to their field and I ask if there are any local customs that they follow that may not be obviously posted elsewhere. I end by requesting that any infractions I commit be brought to my attention, in a friendly manner immediately after my flight.
I have not had any problems of any sort anywhere I have flown and have always received help and assistance if needed.
Sometimes, how you approach a new situation makes all the difference.
