Hi luvtocamp (we do too), We also use parchment paper. We always preheat. In case you haven't figured this out yet, after the oven has preheated, you have to open it up, put your item in, then close it and set the cook time. Even if you have already put the item in before preheating, you have to open the door after it has preheated and close it again to set the time or it just stays on preheat. After you've opened the door and put your item in and closed the door, you have to set the time right away or it all shuts down within a couple of minutes. I thought that was confusing but finally figured it out! Technology can be overrated.
You won't have to worry about snow in September in Wyoming - this is just a cold snap we're having. We were traveling around northern Wyoming all September, and the weather was beautiful the whole time. It does get cool at night in September. What part will you be visiting? It's such a huge state that it's hard to make any recommendations unless we know what you'll actually be near during your free time and how long you'll have. We've been all over in our 36+ years living here, so let us know. We'd love to give you some ideas about our favorite places...it's a beautiful state with so much to see!! We're so proud to live here. September is perfect because most of the tourists have come and gone, so everything is less crowded. Of course, Yellowstone and Devils Tower are a must.
