I'm planning for a road trip and I'm putting all my trust on the members of this site, so please help me.
I'm an international student here in the US, I will finish this may and I'm planning for a road trip with my dad, mom and sister. we will start from champaign, illinois, spring field and st. louis and I want to take them to see DC, NY and niagara falls. in the way to there I would like to visit the best "natureistic" places, anything unusual, mountins, vallies, and so on.
I don't mind going south little bit before going north, maybe as far as SC.
my parents love nature, but they are not so much educated about the American history, so history museums will not be that much attractive for them, however, I'll save musuem visits to DC and spring field, il., I think it will be enough for them ( what do you think? )
