Dear Dan,
I grew up in Miami back in the 50's,60's and 70's and was always planting trees, 
mostly coconuts that sproutd along the beaches and inland waters. I must say 
there are tons of insects and a pool screen would be manditory for edibles. Keep 
the veggies high unlike the desert where you'd crator garden. Keep intouch, I'm 
really curious on the results. Watch out for the gov. coming in and just ripping 
your citrus trees out without warning, because of the medfly.

Ray

  The Great Challenges we now face as a species present the very opportunities 
that are giving birth to Ecological, Psychological, and Spiritual 
Sustainability.
