IO540, it's encouraging that I'm not the only one thinking a bunch of these NOTAMS are pointless (I was worrying that I was missing something!)
FREDA, I also enjoy the planning, and it takes me a couple of hours to really do a proper job too - though like you, that's partly because I enjoy it and quite like spending a bit longer than I really have to on it. That will probably change in due course, but if it means I get 4 hours' enjoyment and only pay for 1, hey, I think that's a bonus
Edit: for "pointless", read "not that relevant to me"... oops!
