There is apparently a place here in town where I can walk in tomorrow morning (they will be open Friday) and do such a donation, so for Kelli's sake, I'll give it a try, if they'll take me. I'm thankful that I can do something to help my sister here, whose health problems make mine look small.
In the meantime, we had a nice Thanksgiving dinner with my family. And I was very thankful that, even without having taken a walk after a traditional dinner (turkey, stuffing, potatoes, gravy, and a small slice of pumpkin pie for dessert), my blood sugar was a perfectly-normal 108. (Lisa and I took a walk down to my old high school afterwards for good measure.)
I'm trying to take it easy this weekend. My hotel room is right next to the pool, so we'll probably hit the hot tub later tonight.
