FlIyter, I just checked the 10-day forecast for Rochester, MN, and though it looks to be quite cold, I don't see any major weather systems in the forecast, so Mother Nature may be on your side for the trip.
You'll certainly be in our prayers, as will our friend Rick who will be there at the same time as you. You'll both have an adventure you'll be able to share with your grandchildren and great grandchildren.
I'm not surprised that your emotions are running the gamut right now. That's to be expected. Once you're there, though, I think you'll find that events start happening quickly and you'll be out of recovery and in your room before you know what happened.
Best of luck to you, and we'll be waiting to here from you when you're back home. Bill
