Notamed with what?
Most notams are a load of crap - stuff like "some plane will be doing a weather survey"... as if the air was not full of planes already.
If you disregard all notams which are irrelevant on the basis of telling us about something which already happens all over the place, what it leaves you with is
- prohibited areas (lots of them this summer - airshows)
- temporary Class A airspace - defunct navaids
- closed airports etc.
and those do matter.
