The brown hills happen in Oregon any time there are no trees.
But I found the answer to everyone's questions, legal-wise. Here's the site.

And here's the answer --
All 50 states have statutes against bigamy (multiple licensed marriages). In most states, bigamy is a felony.
In the following states, bigamy is a misdemeanor. However, once the penalty is paid, you are back at square one.
Alaska
Arkansas
Hawaii (petty misdemeanor-- 30 days in jail)
Iowa
Maine
Missouri
Montana
Nebraska
New Jersey
Ohio
Pennsylvania
Rhode Island (misdemeanor, $1000)
Tennessee
Texas
The following lists are ordered by which states have the most promising statutorily. The first list is the best, the last list is the worst.
The following states, have no statutes against fornication, adultery, or cohabitation, and they also do not recognize common-law marriages.
California
Hawaii
Nevada
Oregon
Washington
The following states have statutes that concern adultery, but none for fornication, cohabitation, or common-law marriage. In some of them adultery is grounds for divorce only. In others the offending spouse simply forfeits any rights to the innocent spouse's estate. In the rest of them, adultery is a crime that can only be prosecuted by the offended spouse. In a successful polygamous relationship, these need not be obstructive. If the relationship fails, however, the statutory adulterer will be charged.
Connecticut
Delaware
Indiana
Kentucky
Louisiana
Maine
Maryland (Adultery results in a $10 fine and is grounds for divorce)
Missouri
New Jersey
Ohio
South Dakota
Tennessee
Texas (Texas does recognize common-law marriages, but apparently only if they are registered with the county clerk)
Vermont
Both states make adultery and fornication misdemeanors, although in Illinois the conduct must be "open and notorious." For interest's sake, we have listed all of the states whose statutes are no worse than Georgia or Illinois. This only means that in these states you are as likely as not, to be able to find a lawyer who will talk to you.
