Sorry but I just don't understand this.
If you have a moving map GPS (yes, I know they are the work of the devil, owned an run by Uncle Sam etc., etc.) with an up to date data-base you really do have to be a half-wit to infringe.
If you look at an up to date map once every ten minutes as well, you need to be a quarter-wit to get into the wrong piece of sky.
Or am I missing something?
