The other thing to keep in mind is that just because a hospital is there is that it cannot take all 200 of us for rotations at one time. It can only take a set ammount depending up on attenidngs and available teaching cases.
The other thing you have to rember is that at no school or most schools will not just rotate at one hospital. My friend who is graduating for UC Davis rotated through UC Davis Med center, Folsom Prision, Sutter, Travis AFB. My cousin at NYMC in his 3rd year now has so far rotated throuhg Westchester, St. Vincents, and some place in connetticurr.
However, regarding DMU if your hell bent on staying in the DSM area you probally will be able to either through the Match or by trading with some one else.
