Healthy soil and sustainable growing

[<activism98201@verizon.net>]

I'm looking to generate a map of farms located within a given radius, perhaps 
showing multiple radii (100 miles, 250 miles etc.).  It's to aid in 
understanding "eat local" distances.

Anyone know of anything (web tool perhaps)?

www.localharvest.org kind of does this, but I'm needing to actually show 
distance lines.


Thanks!
