After his class one evening, we visited our friends who live nearby and the kids enjoyed swimming in their pond, until a thunderstorm chased us all indoors.
(This is a family joke from our trip here two years ago)
The last day, we drove several miles across the lake to visit this custard stand we'd been told about. Rend Lake is so big compared to anything near here. It was a beautiful drive, which is a good thing, since the custard stand was closed when we got there!
