[APWG] Skip the vinegar, and go for Ecological Restoration

Craig and All,

We are involved in ecological restoration. This is a large
valley that we have been clearing for the last five years.
We are in the process of restoring native Hawaiian
ecosystems but we need to stay ahead of the weeds in order
to do so. We are looking for practical alternatives to the
neurotoxic sludge that we are currently using.

Any thoughts or feedback is appreciated.

David Leonard
