Well I lived half my life in Colorado and the other half in Texas so I'll just do both.
To start off, Colorado is beautiful, especially the mountains. So definetly go see those.
Also there is this place called Manitou Springs, it has many neat shops and even this event called the coffin races around October. The main attraction in Manitou (at least to me) is the arcades. They are super fun and I'd spend hours at them.
Some restaurants there are Manitou Brewing Company and The Keg.
If you like to gamble then Cripple Creek is cool as well.
Now as for Texas.....I live in a not so interesting part of the state so I can't really recommend coming here but if you do then here are some places I've gone to that are great:
San Antonio's River Walk
The Alamo, it's a historical landmark
and something from my hometown, The Fort Worth Stockyards
