What is Eureka?Eureka ran from 2006 to 2012. The concept is a town created for all of the great minds to live in and work together. The Oppenheimer descendants still live there. Explosions are normal because you never know what type of experiment is going on. Jack Carter the Sherriff is one of the regular, normal people dealing with a town full of people who are used to being the smartest of smartest. It is a fun show in itself, but it is also great for crossing over with your other fandoms with smart people. You can find several great SGA/Eureka stories at A03.
