The Old Red Museum is a great place to learn about the history and cultural aspects of Dallas County. There are four main galleries with fabulous films that serve as an introduction to the galleries which then tell you about everything from the dinosaurs that once roamed the county to the latest entertainers born and raised in Dallas. There is a hands-on education center (TEKS related education programs are available for groups for an additional charge), and a temporary gallery that features various Dallas-related exhibits. The building also serves as a beautiful site for special events, and the restored courtroom is a great place to hold meetings. While the entrance fees are reasonable, I suggest parking at The Sixth Floor Museum in Dealey Plaza, which is only a block away, and save yourself $4. You can put that money towards your visit to The Sixth (& seventh) Floor.

This was really like travelling back in time to one of the most significant dates in American History. The exhibits consisted mostly of placards to read after listening to the audio tour and a scaled model of Dealey Plaza. It might be difficult to keep the attention of little children as there were few interactive exhibits. Notwithstanding, it still is a place to see just from the shear significance that the area will always hold.
The museum is full of info you probably saw in documentaries or read in the myriad of conspiracy theory books designed to seperate you from your money. I was surprised to see where Zapruder was standing in relation to the grassy knoll. It is more for the curiosity seekers and history buffs. It does address all the theories. overall, a good visit and worth it... but only once.
