i did a two-month $50 total donation this time. I was coming out of Trader's Joe and was stopped by a nature conservancy solicitor. i was planning to only donate a month, but he said that it reflected negatively on them if people signed up for one month, then dropped it immediately so he asked that i do two months before cancelling. so, well, sure, why not. it's been a while since I've done an environmental group anyway and nature conservancy does do good work.
