It's a good call to optimize your prints on smaller sheets, but I'll raise your 13x19 to 13x38 and tell you that you have to take and print some South Florida Landscape Panoramas.
The next time I make it down that way, and who knows when that'll be, I'll bring a couple of sheets of their 13x38 and 8.5x25 panorama paper with me for you to use. I've made a few heron and eagle prints of close ups on the panorama papers, and have even had people ask to purchase them. One of the shots I really want to get is an Everglades shot with a solitary thunderstorm in the photo. If I get what I want with this shot, I'll possible even print it on a sheet of 17x48 (or 17 x 50) matte canvas.
BTW, were forecast to get 4-9 inches of snow or the equivalent of another type of freezing precipitation on Tuesday. The county plans to shut down our bridges starting at noon tomorrow, Tuesday Jan 21. It should be fun. If we get blanket of snow, I'm going to try to get to the local beach for some snow shots. I just have to find where my camera bags were placed in the aftermath of the Christmas decorating frenzy that went on here in December.
