Before I went on the Skimmer Boat Trip back in May I stocked up on memory cards. I bought enough to (hopefully) last through my two week trip to Belgium, Luxembourg, Germany, Austria, Liechtenstein, Switzerland, and France. I think I can do it. Especially if I take it off RAW. I took 2,382 photos on May 12 in New Jersey. That didn't fill up the one card (I bought 4 cards) so I think...I can do it. But it's hard to say. One photo (per view) of a castle is usually enough but I took 5, for example, of this butterfly and hundreds of each individual moving bird.
