[meteorite-list] living near a strewfield

[joseph_town at att.net]

Hi EMan and list,

So a strewnfield does not exist until proven, regardless of the fact that little 
or no effort has been made in the investigation of a given fall/find? I can see 
that. Still, I'd like to believe they're there just as any cold find sets a 
hunter in motion.
