What exit?

So heading to the Great Wolf Lodge yesterday, Steph and I mused how on our first trip there, five months ago, we missed the exit and had to turn around. We were trying to remember which exit to take -- did it say "Grand Mound" or what? From the back of the van comes a voice. "Exit B -- 88," Eddie said.

At least, that's what he remembered. We were amused. Until the exit came into sight. Yup. Exit 88. But no "B" designation. When we left today, however, we glimpsed the exit from the Northbound freeway -- which is the one we took, again, five months ago. That's right. From that direction, there is an A and B designation and our exit was 88 B. I can't remember the number of the exit for our house -- or half the time, where I left my keys. But Eddie can remember an exit from five months ago. He's an odd bird, but a very nice bird to have around.
