Turtleboard,
Trips to radiology can be very educational (although I admit I'm biased since I plan on entering the field). It seems your residents weren't as good about teaching you about findings on radiologic studies as mine were.
Clinicians from almost every field must have a basic understanding of radiologic findings. If you're on call in your intern year and you get a chest x-ray or abdominal series or abdominal CT for an urgent situation, you don't have the luxury of waiting for a radiology report. If the rads resident on call is busy doing an ultrasound for 45 minutes (most hospitals don't have a tech on call!), you're gonna have a hell of a time getting him to take a look. You need to be able to tell if a patient has CHF with pulmonary edema, a bowel obstruction, bowel perforation, ruptured spleen, etc. You should be able to see these basic findings on your own and cannot do so without going down to the "cave" and looking at some films during medical school. Also, the clinical information you give the radiologist can often help him/her decide what the most likely finding is on a study since the requisitions sent down give very brief and often inaccurate histories.
Try going down there after the film have already been read and dicatated. If there are interesting findings, you should see them so that you can recognize them in the future. Plus, after they are dictated, its usually easy to find the films because they have been filed away.
Hope you don't mind these tips from a future radiologist on how to use your radiology department for your education. You can read at home, you can't see films at home!
