Thanks Rentacow,
Yes, I know I could 'guess' the coordinates of all the ranges - but I was looking for a list of the coordinates for all of the marked training ranges - W291, TMA-P6, etc...
I'm still looking too. In Australia the Aviation authority publishes the coordinates of military ranges - including Navy ranges. But I'm not sure how the Americans do it.
I've tried to navigate the California NOTAMS website - but can't seem to find them.
Thanks for your help though
