Larry, While I regret the loss of your friend I would be wary of "good" neighbourhoods also. I grew up in the slums. Somehow through chance & circumstance I became quite the yuppie and moved in upper circles. I confess that in many ways I found the slums more honest & direct. It's always a good idea to watch your back but, again, paranoia can just paralyze you and is rather counter-productive. Absolutely a no-win situation because if nobody else does it to you you do it to yourself...
