Having grown up through the 60's and 70's I was familiar with the JPL so when I found out tours are available I jumped at the chance to visit.
The tour takes in mission control, assembly building and the museum. The guide is very knowledgeable and questions encouraged.
It's a city or campus depending on your view and 6000 people work here. Security is strict but not over bearing.
Parking is limited and beware that the souvenir shop closes before the tour ends.
