The attitude towards marajuana is totally different in Humbolt and Mendocino Counties...both from a legal and populace point of view. I almost moved t Ukiah about three years ago...Mendocino County is beautiful. However, a good portion of the citizenry is stoned the better part of the day. When we went out looking at houses or visiting wineries (two of my favorite things to do, by the way) almost every local contact told us about the impact the cultivation of marajuana has on the local economy and things like crime.
We were, in fact, told that we should not take any hikes in the woods or backcountry at that time of the year. It was around this time, I believe. It seems this is around harvest time and the "farmers" don't take kindly to anyone crossing their path. And, they are armed to the hilt. If you recall, there was a county official killed just a couple months ago...the alleged person is in custody.
Don't get me wrong, I love the area...I miss Northern California very much; but you have to consider carefully exactly where you want to live in some of the communities in Mendocino and Humbolt Counties (I guess you do in all areas; but not all areas can tout themselves as the "Pot Growing Capital of the States"). Find yourself a good agent and rely on their knowledge of the place.
