Hey good idea. I find the darker green one a bit harder to look at - bit of an optical thing going with the green and white. Maybe that's a good thing to get attention?
I think it's good to incorporate the TM symbol as we'll have to do so somewhere.
Not at the office today, and I'll ask others. The fences idea is good but it might concern some people. Because a few groups have over emphasised the role of fences, and the public sometimes react negatively to things like the dog fence and the barrier fences - I'm not saying ditch it (I think it works well as a design elecment) but I'll ask a few opinions.
Thanks for the effort.
