Welll.....Sorta... To me, it's almost in both directions at the same
time it's so quick. I guess you could consider the streamer as the
first part of the strike, but you need a down leader to complete
the strike. The downleader connects with the streamer, and you
have a strike, which can pulse more than once. If you have a streamer,

and no leaders find it, you ain't gonna have a strike. So it takes
both ends to make a strike. Saying it starts at the bottom is semi
misleading, to me anyway...It really goes both ways, and they meet
in the middle to complete a strike. Or thats the way I see it...
But, the streamer does form first of the two, so I guess that would
make it seem to start at the bottom... MK
