Thanks guys, I guess I'm on the right track. I will carry a cell-phone and some Snickers bars. (We have two Type 1 diabetic daughters and the younger one says, "Why waste a good low; eat chocolate.") Our tandem is a Cannondale MT800 and features wide wheels and tires. It should deal with the possible muddy conditions quite well.
I usually test before each meal and at bed time. I figure I'll be testing 8-10 times a day while on tour. I also probably will cut back on the amount of my meds a bit. I manage my diabetes and my doctor goes with the program.
He told me he wishes he could take the time to go with us.
Doc
