I'm in a treed area, no clear view here.
No, the constellation Perseus is just the general direction from which the meteors will be flying away from, you'll see them all over the sky, no particular region or cardinal direction.
Right, but, until that comes over the horizon, you won't see the meteors coming from all over the sky....so IIRC, you have to wait until Perseus comes over the horizon to be in the middle of that cloud of meteors...so that you can see the meteorites.
Otherwise, you could just see them as soon as the sky was dark enough, which is not really the case except by coincidence, etc.
I think Sunday/Monday is it for this pass through of the comet's tail.....so, if you want to see it, depending on your time zone, etc...this is the time.
