Wow, this is sure a break from the tedium of the board. (Not that there's actually boring discussions here; merely a reference point).
Actually when I read your post, I got a few chills. Perhaps, I am a believing, trusting soul while others attempt to read too far between the lines where there, in this case, is no existence at all. You did not mention how long ago this was. For some reaon, I would find this information interesting; kind of like when I meet someone; I always try to find out where they live, what they do for a living and what they like to do when they are not working.
So, Bowser, the questions remain; are there any additional details to this occurance that you could impart? How early in the AM? Nearly dawn, mid morning? Was the sky gray or cloudy. My mental image now is that it is very early in the morning and no one else is around...the day has yet to begin for many.
I think this, beacuse, I cannot imagine this occuring whilest the sun is high in the sky, the birds are chirping away and the maintenance crew cares for the lawn.
When you say she was dressed in '40's garb, you mean a long dark dress with a hat and/or a shawl or a wrap.
I personally would enjoy hearing more of it!
