I spent a few weeks rotating through different specialties in an "externship" at one of our local hospitals offered exclusively to those finished with 1st year. It was a blast and I got to see what it's really going to be like during years 3 and 4. We were paired up with Residents/Interns for each week and followed them around on rounds and to conferences. I did rotations in EM, Hem/Onc, IM, and Cardio. Pretty much everyone else who participated had a blast. Each rotation was a week long, so I still had plenty of time for my road trip and lying on the beach getting tan.
If you can find a program in your area, I would highly recommend it. It'll help you narrow down what you want to do and help you be a little more prepared for the rotations...
