They migrated for different reasons:&nbsp; They sought free land in the Oregon Territory, religious freedom in the Great Salt Lake Valley, and free gold in California. These pioneers left behind not only trails, but important stories as well, stories that are significant to U.S. history.<br /> Fri, 09 Mar 2012 20:41:27 +0000 Alex Rose 20825 at http://wyomingpublicmedia.org National Historic Trails Interpretive Center - Casper
