I detect some jealousy... I'm at about 180 miles on this tank. I was SURE I would hit reserve on the way home, but I didn't! I'll fill it up in the morning (or the following, depending on the rain) and calculate my MPG's. Also, to the OP, I would encourage you to get out and ride in the rain on the freeway, on purpose some more before heading out on that trip. I know you weren't very comfortable riding in the rain on the photo hunt, and the chances are good that you will hit rain while out on your trip. It took me a while to get comfortable riding in heavy rain, and even still I don't corner very hard in the rain (not saying that I do on the dry roads either.)
