Here are two more regional offers from Best Western.

1,000 points per night, up to 4,000 points California, Nevada and Hawaii to Jan 31, 2013

1,500 points per night, up to 6,000 points to Jan 31, 2013 in Frontier States defined as Arizona, Colorado, Kansas, Missouri, Nebraska, New Mexico, Utah.

There are probably other offers for other regions, but I was unable to locate any other regional offers in a quick search.
