Very Fun. Are there a couple of surfaces to the
right with the first discharge? Seems very short
for slap-back echo within the cloud itself,
unless it was _really_ close. The second
discharge seems more like echo within the clouds.
Terrific relief and movement-- Recorded with your
wedge? Two cardinals emerging from the illusion
of one, the back-up warning closure. :-)!
I guess we know what we could test for now to pin
it down to the 183's or HiMD or both. Rob D.
