It's kinda cool to stand on the ground where Sacajawea, Lewis & Clark and Corps of Discovery camped over 200 years ago. Heritage days takes place Sept. 28-29. There will be Lewis & Clark reenactments, Mountain Men, Native Americans, wood carvers, a steam engine, birds of prey and more.It's a free event, but you'll need a Discover Pass or pay a $10 daily park entrance fee. Get all the details on the Sacajawea State Park web page HERE.
