So do you know anything about Colorado?
It's a very mountainous state, it contains most of the southern Rocky Mountains. Have you ever been there?
no I haven't but my parents are planning a big trip there within the next year so I'm really excited for them
It sounds like a cool place to visit. Besides the mountains, there is the Colorado River, which the state is actually named after. 
they are planning on taking a train ride through the mountains which sounds amazing!  
That does sound amazing! Colorado is a huge state, it's actually the 8th largest state geographically. I'll bet they will love their trip!
Wow I didn't know it was the 8th largest state.  that is neat.  
Yes, it's only the 21st most populous state though. There are a lot of wide open spaces where not many people live.
That is good though that they left it open and beautiful for people to explore
Yes, it's pretty cool. There's some neat history there too. Colorado became a state in 1876.
