Well, why don't I chime in along with the rest of my esteemed colleagues. To answer the OP's question- one good idea might be to check out our student affairs website at:
http://www.som.tulane.edu/student.html . Check out the electives (in the Office of Student Affairs link), the MD/MPH program, click on "student organizations" and see all the different things you can do outside of school, etc. This will give you a good idea as to what's out there, in addition to the other things already mentioned.
What I like about this place is that there's something for everyone. You wanna shadow surgeons, cool. You wanna intubate and put in IV's (in your first year!), cool. You wanna do H&P's at local halfway houses, cool. You wanna spend time tutoring low-income kids, cool (very fun & rewarding). You wanna teach CPR & BLS in public schools, cool. You wanna play in the ER at Charity, cool. You wanna get an MPH, cool. You wanna double down your 11 on a dealer 6, cool. You name it, you can do it. And if there isn't already an organized program to do what you want, bring it up to the faculty, and chances are you can organize it yourself. They got a sports medicine shadowing program going last year that way.
The bottom line is that this is a great school for becoming a clinician. You're in a sane, non-competitve environment, with a ton of things to do outside of school, with great, supportive faculty. Put it this way- where else is it a Friday tradition to grab some pitchers with your professors? Work hard, play hard, baby.
