Yes, have read/scanned every issue. I have an online subscription to Permaculture Magazine and it saves a lot of money.
With an online subscription, I gained access to every back issue, plus the current Spring 2011 issue. It costs about $7.00 U.S. every 3 months and it can be canceled anytime. Even though it focuses on the U.K., the concepts are usually workable in the U.S.
