I know this is not at all related to Astros news, but I was hoping to get some help from the locals. We will be in Houston next week and are setting aside an entire day to go to NASA.
Does anyone have any suggestions on what to be sure and do there...should we take the day long tour? Or should we just go and look around ourselves not with the help of a tour guide?
What are the must do's there, and what should we not waste our time on?
Any help is appreciated.
