Before we purchased a digital camera, I used approximately 12 rolls of 36 exposures per week-long trip (much to my DH's consternation...processing was a nightmare!). I am a photography (and scrapbooking) nut! With a regular camera, you are never quite sure the picture "turned out" the first time, so if one was good, two or three were even better. Besides, film in the park is so expensive that it's better to bring more than not enough! We, too, have gone digital so that eliminates the worries of getting the perfect shot and having blurry ones, etc.
