Holy cow.
It was an interesting experience ;)
We were quite rough on the greenies. They were very upset with us. We got threats from Earth First, Sierra Club Legal Defense Fund, ALF/ELF and a few others. Time Magazine really ripped me/us in their 97 or 98 Earth Day issue after we cost one group 6 figures in funding.
But one can only be intimidated if one allows themselves to be intimidated. Laz pointed that out perfectly.
