Pretty soon in the winter quarter I'll have the chance to take an undergrad course on either Solid State physics or Nuclear physics. Both fields are of interest to me. I'd like to choose the one that has more research currently being done on it though. So that if I end up still liking it I can have a lot of opportunities to enter a grad school that is researching the field and knowing a bit more on the subject than maybe a few other students can give me an edge. The more opportunities the better. Thanks to anyone for a reply.
