US based activism group "change the landscape"

I saw a billboard on rt 22 in New york State recently that caught my eye as i whizzed by; some sort of pro-legalization group with a very cryptic website "changethelandscape.com" or something of that sort. i was not able to find it in a search. so i thought i'd pick the collective minds of the good folks on this board in the hopes that one of you may know what i am referring too.

Any ideas?

well 32 days 9 months and 2 years later u'll finally get a reply and i have no idea lol.
