Eh. Im all for history but this place kinda toots its own horn a little much. "Pueblo ruins" is a stretch. Faint remnants and clearings w/ a video explaining what used to be there is more accurate.
On the plus side it's cheap (or free some days, i think) and its a good short trip if you have kids you'd like to expose to a little culture. I appreciate the educational value of this place, but it got kind of boring trying to imagine what it looked like instead of actually being able to see much. They have some neat reproductions and a lot of information, and the museum is decent.
