We never had one of them newfangled digital reader boards. We had to pull the individual letters and put them up, one by one, hoping the person tall enough to do so was also literate enough to get it right (it really ticks folks off when they get off the ladder and are told to speel it rite, pleez).
Of course, since it's computerized there's no possibility it was inaccurate. You must have been having quite the hotflash to keep yourself and DH warm and comfortable. (Should I lean harder on the sarcasm button?)
